I strongly agree. This "datatype deduction" is really ugly because:
a) it's not always correct
b) it is an arbitrary list of types, whose usefulness I doubt. HOw often
would you associate real numbers as properties? Yes, it could happen, but
enumerated types would be more likely.

Special-casing might be marginally useful in some cases (and make things
harder in other), but I don't think its worth the maintenance. You know,
we add a new svn: property. Then forget to update the DTD and get
complaints about invalid XML...

+1.
