By "I wrote my code to make it so" I meant both the direct typing of 
XML code, and the writing of Java/PHP/C#/Fortran/Basic etc. code that 
generates the document. In both cases, I think it is generally 
possible to assert that the code will or will not use the new name 
characters if this is an important assertion for you to make.

As to IDs, this is a bit of a problem but not a big one. It affects 
only validity, not well-formedness. I am much less concerned with the 
prospects of valid 1.1/invalid 1.0 than well-formed 1.1/malformed 
1.0. Remember, you can use all the characters at issue in XML 1.0 
documents *today* in both PCDATA and attribute values.
