I promised Valerio I'd send the next version of the Attribute Exchange Profile to the list on Monday (and it still is, local time :) I tried to incorporate everyone's comments, but if I missed something, please let me know and I'll fix it. Tom Scavo NCSA PS. On a technical editing note, I wasn't able to number the appendices so that they appear in the TOC, so if someone knows how to do that, please do. Thanks.
