Just wondering: Since we have reifiable21 (for XTM 2.1) and reifiable2
(for XTM 2.0) wouldn't it be nice to drop the reifier-attribute in the
XTM 2.1 schema and to allow the reifier-element for XTM 2.1 only? XTM
2.1 parsers would still be required to interpret the reifier attribute
iff they read a XTM 2.0 topic map.

Or would that move too hard to communicate?
