1. A computer-implemented method for representing transaction processing system messages as XML documents, the method comprising:generating an XML document template from a transaction processing system message definition, the message definition representative of the syntax and semantics for messages exchanged with the transaction processing system; merging a transaction processing system message with the generated template to produce a corresponding XML document; and wherein generating an XML document template comprises: obtaining a transaction processing system message definition; obtaining a DTD for representing arbitrary transaction processing system message definitions; and parsing the transaction processing system message definition using the DTD to generate an XML document template corresponding to the transaction processing system message definition. 2. A computer-implemented method for representing transaction processing system messages as XML documents, the method comprising:generating an XML document template from a transaction processing system message definition, the message definition representative of the syntax and semantics for messages exchanged with the transaction processing system; merging a transaction processing system message with the generated template to produce a corresponding XML document; and wherein generating an XML document template comprises: obtaining a transaction processing system message definition; obtaining a DTD for representing arbitrary transaction processing system message definitions; compiling the transaction processing system message definition with an option configured to produce an associated data (Adata) file; and parsing the Adata file using the DTD to generate an XML document template corresponding to the transaction processing system message definition. 3. The method of claim 2, wherein the Adata file comprises a transaction processing system message definition in a format substantially semantically equivalent to program source code from which the transaction processing system message definition originates.4. The method of claim 2, wherein obtaining the transaction processing system message definition comprises:extracting the transaction processing system message definition from one of an application source code file and a copy file. 5. The method of claim 2, wherein the step of obtaining the DTD comprises:creating a UML object model for representing arbitrary transaction processing system message definitions; and processing the object model using an XMI utility to generate the DTD. 6. The method of claim 2, wherein the merging step comprises:identifying a placeholder within the XML document template for receiving a corresponding value from the transaction processing system message; reading the value from the transaction processing system message; and inserting the value into a location within the XML document template indicated by the placeholder. 7. The method of claim 6, wherein the placeholder comprises an XML tag.8. The method of claim 6, wherein the identifying step comprises:checking the placeholder for an associated tag indicating that a corresponding value exists within the transaction processing system message. 9. The method of claim 6, wherein the placeholder has an associated tag indicating the size of the corresponding value within the transaction processing system message, the reading step comprising:reading a portion of the transaction processing system message corresponding to the indicated size. 10. A system for representing transaction processing system messages as XML documents, the system comprising:a processor; a template generation module configured to generate an XML document template from a transaction processing system message definition, the message definition representative of the syntax and semantics for messages exchanged with the transaction processing system; a merging module configured to merge a transaction processing system message with the generated template to produce a corresponding XML document; and wherein the template generation module comprises: a parser configured to obtain a DTD for representing arbitrary transaction processing system message definitions and parse the transaction processing system message definition using the DTD to generate an XML document template corresponding to the transaction processing system message definition. 11. A system for representing transaction processing system messages as XML documents, the system comprising:a processor: a template generation module configured to generate an XML document template from a transaction processing system message definition, the message definition representative of the syntax and semantics for messages exchanged with the transaction processing system; a merging module configured to merge a transaction processing system message with the generated template to produce a corresponding XML document; and wherein the template generation module comprises: a compiler configured to compile a transaction processing system message definition with an option configured to produce an associated data (Adata) file; and a parser configured to parse the Adata file using a DTD for representing arbitrary transaction processing system message definitions to generate an XML document template corresponding to the transaction processing system message definition. 12. The system of claim 11, wherein the Adata file comprises a transaction processing system message definition in a format substantially semantically equivalent to program source code from which the transaction processing system message definition originates.13. The system of claim 11, further comprising:a message definition extractor configured to extract the transaction processing system message definition from one of an application source code file and a copy file. 14. The system of claim 11, further comprising:a modeling tool configured to create a UML object model for representing arbitrary transaction processing system message definitions; and an XMI utility for generating the DTD from the UML object model. 15. The system of claim 11, wherein the merging module is further configured to identify a placeholder within XML document template for receiving a corresponding value from the transaction processing system message; read the value from the transaction processing system message; and insert the value into a location within the XML document template indicated by the placeholder.16. The system of claim 15, wherein the placeholder comprises an XML tag.17. The system of claim 15, wherein the placeholder comprises an associated tag indicating whether a corresponding value exists within the transaction processing system message.18. The system of claim 15, wherein the placeholder has an associated tag indicating the size of the corresponding value within the transaction processing system message.19. An article of manufacture comprising a program storage medium readable by a processor and embodying one or more instructions executable by the processor to perform a computer-implemented method for representing transaction processing system messages as XML documents, the method comprising:generating an XML document template from a transaction processing system message definition, the message definition representative of the syntax and semantics for messages exchanged with the transaction processing system; merging a transaction processing system message with the generated template to produce a corresponding XML document; and wherein the generation step comprises: obtaining a transaction processing system message definition; obtaining a DTD for representing arbitrary transaction processing system message definitions; compiling the transaction processing system message definition with an option configured to produce an associated data (Adata) file; and parsing the Adata file using the DTD to generate an XML document template corresponding to the transaction processing system message definition. 20. The article of claim 19, wherein the transaction processing system message definition comprises program source code in a language selected from the group consisting of COBOL, PL/I, Assembler, and Pascal.21. The article of claim 19, wherein the Adata file comprises a transaction processing system message definition in a format substantially semantically equivalent to program source code from which the transaction processing system message definition originates.22. The article of claim 19, wherein obtaining the transaction processing system message definition comprises:extracting the transaction processing system message definition from one of an application source code file and a copy file. 23. The article of claim 19, wherein the step of obtaining the DTD comprises:creating a UML object model for representing arbitrary transaction processing system message definitions; and processing the object model using an XMI utility to generate the DTD. 24.
