We've never been asked before for such a feature. We can add it, but if
you want it immediately, just hack the source files to pass a flag through
(similar to the other Xerces options we support).

| Subject: reusing validator ala Xerces
|
>---------------------------------------------------------------------------------------------------------------------------|
Xerces 1.6.0 provides a mechanism for reusing a validation grammer across a
number of XML parses. This is done via the reuseGrammar parameter of the
DOMParser::parse() method. Does Xalan 1.3 expose similar functionality
through
its public APIs?
This is useful in cases where a single parser/transformer instance is being
used
to process many XML documents, each of which is known to use the same DTD,
say.
In this case, it would be nice to avoid re-parsing the DTD on each
iteration
after the first.
As far as I understand the Xalan documentation, I can explicitly use Xerces
to
produce the DOM tree as input to XalanTransformer::transform() -- and thus
exploit Xerces' "reuseGrammar" mechanism -- but the Xalan documentation
also
claims that Xalan performs better when using its own internally constructed
DOM
tree. Thus I appear to left to choose between two sub-optimal scenarios.
