1. A method implemented by a client device for managing electronic documents including metadata related to broadcasting multimedia content, the method comprising: receiving an electronic document at the client device, the electronic document including metadata related to broadcasting multimedia content and having a defined structure including two or more structural elements, each of the two or more structural elements associated with a respective identifier and a respective version value representing a corresponding date;sending a request from the client device to a server for an update to the electronic document, wherein the request includes a first version value representing a first date;receiving an update document at the client device in response to the request, wherein the update document includes both updated information and invalidity information for the electronic document, wherein the updated information includes one or more structural elements updated after the first date, and the invalidity information includes a first identifier and a second version value representing a second date to indicate invalidity of a first structural element that has the first identifier and is associated with the second date, and wherein said first identifier is reused in the update to the electronic document for identifying a second structural element other than the first structural element; andprocessing the received invalidity information at the client device to identify the invalid first structural element based on the first identifier and the corresponding second version value. 2. The method of claim 1, further comprising: deleting the invalid first structural element at the client device. 3. The method of claim 1, wherein said electronic document is in XML format. 4. The method of claim 1, wherein the first version value and the second version value include a numerical representation of a corresponding calendar date. 5. The method of claim 4, wherein the numerical representation of the corresponding calendar date is expressed in the form of YYYYMMDD, wherein YYYY, MM, and DD are numerical expressions of year, month, and day, respectively. 6. A method implemented by a server for managing electronic documents including metadata related to broadcasting multimedia content, the method comprising: providing an electronic document to a client device, the electronic document including metadata related to broadcasting multimedia content and having a defined structure including two or more structural elements, each of the two or more structural elements associated with a respective identifier and a respective version value representing a corresponding date;receiving an update request including a first version value representing a first date from the client device for an update to the electronic document; andproviding an update document to the client device in response to the update request, wherein the update document includes both updated information and invalidity information for the electronic document, wherein the updated information includes one or more structural elements updated after the first date, and the invalidity information includes a first identifier and a second version value representing a second date to indicate invalidity of a first structural element that has the first identifier and is associated with the second date, and wherein said first identifier is reused in the update to the electronic document for identifying a second structural element other than the first structural element. 7. The method of claim 6, wherein said electronic document is in XML format. 8. The method of claim 6, wherein the first version value and the second version value include a numerical representation of a corresponding calendar date. 9. The method of claim 8, wherein the numerical representation of the corresponding calendar date is expressed in the form of YYYYMMDD, wherein YYYY, MM, and DD are numerical expressions of year, month, and day, respectively. 10. A software product including instructions tangibly embodied in a non-transitory computer readable medium to cause a client device to perform operations for managing electronic documents including metadata related to broadcasting multimedia content, the operations comprising: receiving an electronic document at the client device, the electronic document including metadata related to broadcasting multimedia content and having a defined structure including two or more structural elements, each of the two or more structural elements associated with a respective identifier and a respective version value representing a corresponding date;sending a request from the client device to a server for an update to the electronic document, wherein the request includes a first version value representing a first date;receiving an update document at the client device in response to the request, wherein the update document includes both updated information and invalidity information for the electronic document, wherein the updated information includes one or more structural elements updated after the first date, and the invalidity information includes a first identifier and a second version value representing a second date to indicate invalidity of a first structural element that has the first identifier and is associated with the second date, and wherein the first identifier is reused in the update to the electronic document for identifying a second structural element other than the first structural element; andprocessing the received invalidity information at the client device to identify the invalid first structural element based on the first identifier and the corresponding second version value. 11. The software product of claim 10, wherein said electronic document is in XML format. 12. A software product including instructions tangibly embodied in a non-transitory computer readable medium to cause a server to perform operations for managing electronic documents including metadata related to broadcasting multimedia content, the operations comprising: providing an electronic document to a client device, the electronic document including metadata related to broadcasting multimedia content and having a defined structure including two or more structural elements, each of the two or more structural elements associated with a respective identifier and a respective version value representing a corresponding date;receiving an update request including a first version value representing a first date from the client device for an update to the electronic document; andproviding an update document to the client device in response to the update request, wherein the update document includes both updated information and invalidity information for the electronic document, wherein the updated information includes one or more structural elements updated after the first date, and the invalidity information includes a first identifier and a second version value representing a second date to indicate invalidity of a first structural element that has the first identifier and is associated with the second date, and wherein the first identifier is reused in the update to the electronic document for identifying a second structural element other than the first structural element. 13. The software product of claim 12, wherein said electronic document is in XML format.
