1. A vane assembly for a gas turbine engine, comprising: a first vane;a second vane, wherein each of said first vane and said second vane includes an inner platform, an outer platform and an airfoil that extends between said inner platform and said outer platform, andwherein said first vane is attached to said second vane at least at one of said inner platforms and said outer platforms with a first attachment mechanism and a second attachment mechanism; wherein at least one of said first attachment mechanism and second attachment mechanism includes a bracket. 2. The vane assembly as recited in claim 1, wherein each of said inner platforms and said outer platforms include a leading edge rail and a trailing edge rail. 3. The vane assembly as recited in claim 2, wherein said first attachment mechanism mechanically attaches one of said leading edge rails and said trailing edge rails of said first vane and said second vane and said second attachment mechanism mechanically attaches the other of said leading edge rails and said trailing edge rails of said first vane and said second vane. 4. The vane assembly as recited in claim 2, wherein mate faces extend between said leading edge rails and said trailing edge rails of said first vane and said second vane. 5. The vane assembly as recited in claim 4, wherein said mate faces are free of attachment openings. 6. The vane assembly as recited in claim 2, comprising a plurality of attachment openings that extend through one of said leading edge rails and said trailing edge rails of said first vane and said second vane. 7. The vane assembly as recited in claim 2, wherein said airfoils extend in chord between said leading edge rails and said trailing edge rails. 8. The vane assembly as recited in claim 1, wherein said bracket bridges a parting line between said first vane and said second vane. 9. The vane assembly as recited in claim 1, wherein said vane assembly is incorporated in a turbine section of said gas turbine engine. 10. The vane assembly as recited in claim 1, wherein said vane assembly is incorporated in a compressor section of said gas turbine engine. 11. The vane assembly as recited in claim 1, wherein said first attachment mechanism is a different mechanism than said second attachment mechanism. 12. The vane assembly as recited in claim 11, wherein said vane assembly is incorporated in a compressor section of said gas turbine engine. 13. A vane assembly for a gas turbine engine, comprising: a plurality of vanes each having a platform that extends between a leading edge rail and a trailing edge rail, and each vane of said plurality of vanes is attached to an adjacent vane at least at one of said leading edge rail and said trailing edge rail with a first attachment mechanism including a bracket. 14. The vane assembly as recited in claim 13, wherein each vane of said plurality of vanes is mechanically attached to said adjacent vane with said first attachment mechanism and a second attachment mechanism that is different from said first attachment mechanism. 15. The vane assembly as recited in claim 14, wherein said first attachment mechanism mechanically attaches one of said leading edge rails and said trailing edge rails of each of said plurality of vanes and said second attachment mechanism mechanically connects the other of said leading edge rails and said trailing edge rails of each of said plurality of vanes. 16. The vane assembly as recited in claim 13, wherein said vane assembly is incorporated in a turbine section of said gas turbine engine. 17. A method for providing a vane assembly for a gas turbine engine, comprising the steps of: attaching adjacent vanes of the vane assembly at least at one of an inner platform and an outer platform with a first attachment mechanism and a second attachment mechanism; wherein at least one of said first attachment mechanism and second attachment mechanism includes a bracket. 18. The method as recited in claim 17, wherein each of the inner platform and the outer platform include a leading edge rail and a trailing edge rail, and comprising the step of: positioning one of the first attachment mechanism and the second attachment mechanism at the leading edge rail; andpositioning the other of first attachment mechanism and the second attachment mechanism at the trailing edge rail to attach the adjacent vanes of the vane assembly. 19. The method as recited in claim 17, wherein the second attachment mechanism includes a pin-socket connector. 20. A vane assembly for a gas turbine engine, comprising: a first vane;a second vane, wherein each of said first vane and said second vane includes an inner platform, an outer platform and an airfoil that extends between said inner platform and said outer platform; andwherein said first vane is attached to said second vane at least at one of said inner platforms and said outer platforms with a first attachment mechanism and a second attachment mechanism, said first attachment mechanism including a bracket and said second attachment mechanism including a pin-socket connector. 21. A vane assembly for a gas turbine engine, comprising: a first vane;a second vane, wherein each of said first vane and said second vane includes an inner platform, an outer platform and an airfoil that extends between said inner platform and said outer platform;wherein said first vane is attached to said second vane at least at one of said inner platforms and said outer platforms with a first attachment mechanism and a second attachment mechanism; andwherein said first attachment mechanism includes a bracket and said second attachment mechanism includes a pin-socket connector, said bracket bridging a parting line between said first vane and said second vane.
