Removed the new attributes from AEAnnc

At SDS 57.4 it was agreed that the upper case T version should be used.  We are making the change to the schemas in 3.28 as this is the first time that this attribute has been introduced, and it might cause confusion to have it change in 3.29.

TS-0004 and TS-0001 will be updated to use T in subsequent drafts.
