Hi Mark,
Xalan's default implementation of the source tree _is_ thread-safe. The
default implementation of compiled stylesheets is also thread-safe.
There is no way to modify the default implementation of the source tree, so
all use is read-only.

XalanTransformer::CompiledStylesheet?

The transformer caches both sources and compiled stylesheets. You could
get
around this by having a global instance of the transformer and using both
compiled stylesheets and sources from that (application permitting of
course), or you could extract code from XalanTransformer, or copy/hack up
the thing to create a custom version.
I do the latter (the functions aren't virtual/members are private so it's
not possible to derive and override), and cache both sources and
stylesheets
outside of the transformer object.
I'm not aware of anything that says that parsed sources are thread safe;
however I'm reasonably certain that if they are used in a read only fashion
there shouldn't be a problem. (Someone please tell me if this isn't the
case!)
