ansi character list

To give you a non-MS area where occasional non XML characters may appear
inside strings: Look at the current ANSI/ISO proposals for serializing
relational data into XML. None of the database companies (Oracle, IBM,
Sybase, us etc) want to encode strings as base64.

To answer your question below: Assuming that we could at least allow to
use a char entity for an invalid XML char. That would already help.

Best regards

PS: Please cc me directly. Otherwise I will not see the answer until
several weeks later...
