Such as Simple Network Markup Language (SNML) [1], which declares an "id"
attribute as CDATA.  You may find a bunch of others by just searching
with the keywords "id CDATA" - perhaps that's because of the limitation
of the "Name" production, as Norm pointed out.

For example, even within the W3C, specs like P3P, VoiceXML and SSML
declare the "name" attribute on some elements as ID.  XML Signature
and XML Encryption use an "Id" attribute, not "id".
