Disabling DTM?

[Vl...@bnz.co.nz]

Hi,
I have a stylesheet extension that relies on ability to do
getElementsByTagName on an element (not mine, so "don't use it" won't work
for me).
It seems to work ok in some cases (mostly when I do DOM based
transformation),  but when I run it in small app which needs stylesheet
chaining (using XMLFilters & SAX), it dies with a DTMDOMException - which
is quite understandeable as there the Element implementation is
DTMNodeProxy. In the other (working) case the Element is
DefferedElementNSImpl.
So, I'm wondering how the implementation is choosen and whether I can
affect it somehow (so that I can still use XMLFilters).
Thanks,
Vlad
