I suggest this should be read-write for parsers that support XML 1.1.
I have a need to sometimes require documents to be 1.0, and right now
setting that up with a parser that supports 1.0 is a royal PITA.

I suggest that this property be a String rather than double. Several reasons:
1. Long term, it may not always be parseable as a double (1.1.1 anyone?)
2. Double equality comparisons are very tricky. String comparisons
are much simpler.
3. It's not hard to convert a String to a double if you need that for
some reason.
4. It's not really possible to make the value of the property a
primitive double in Java. It would have to be a Double. Better to
just make it a String, which is a little easier to deal with in code.
