I agree that it would be better if SAX allowed features to be set after reading
the XML header, especially if any extra pseudo-attributes are put in
(no flames please).  

But the http://xml.org/sax/features/validation  cannot be changed during parsing.
See the last paragraph of    SAX2 Standard Feature Flags  at
http://www.saxproject.org/apidoc/org/xml/sax/package-summary.html

"Unless otherwise specified here, implementations may support changing current values of 
these standard feature flags, but not while parsing. "

which is also commented on in Brownell's O'Reilly book SAX2 at page 87

Of course, there is an "is-standalone" flag, which may allow some kinds of hacking
around the problem.  Am I completely off-track here: is there some workaround
I am missing?

Cheers
