New version of interop document

Dear all,

I attach a new version of the document defining test cases.

I appologize for not just uploading it into the CVS, but I have not been 
able to do that... I will try to solve the CVS stuff as soon as I come 
back from holidays.

Some issues worth to mention:

1. I have introduced a new section on schema-based xpointers.

2. I have also introduced test cases on differences between RFC 4514 and 
RFC 2253, as identified by Sean in 
http://lists.w3.org/Archives/Public/public-xmlsec-maintwg/2007Jul/0024.html.

3. I think that I have clarified something on the test cases on 
Distinguished Names. The idea is that for positive test cases, we have a 
Distinguished Name as input and a string as output, and that in hte 
negative test casee we have a bad string as input (a string that breaks 
some rules of RFC 4514 or XMLSig) and that the tools catch the error.

Again, I appologize for not having managed to use the CVS.

Regards

Juan Carlos.

PSD: I will forward privately to Frederick and Thnomas the whole bunch 
of doucments that I use to produce the html, so that they may put them 
in the CVS and the documents be accessed and edited by anybody.
