SAX2 and XSLT processors

[Oren Ben-Kiki]

I have raised this issue before, and somehow it didn't get very far. But I
feel that a standard API for XSLT processors , in the spirit of SAX, would
be very helpful.

One interesting way for doing it would be to build upon the SAX2 extension
mechanism, providing a standard SAX2 feature called
http://xml.org/sax/features/xslt-transformation and a write only property it
uses, called http://xml.org/sax/properties/xslt-stylesheet which takes an
InputSource value.

I like this approach since it meshes well with the SAX2 framework. Given
that XSLT processor writers will need to adapt their code to SAX2 anyway,
using this opportunity to get a standard API to such processors seems like a
good idea. The amount of work required seems pretty small, at least for an
XSLT processor which is already built on top of a SAX parser and produces
SAX events as the results - these are the only ones which should be
integrated into this framework, anyway.

There remains the question of how to obtain a SAX2 parser supporting XSLT -
say for example I have both XP and XT in my system, I'd expect XP to be the
default SAX parser. However this is an open question in the current SAX2
interface for all extensions, not just for XSLT, so we can wait until it
gets resolved in general.

David Megginson has started writing the SAX2 documentation, listing standard
features and properties (see http://www.megginson.com/SAX/SAX2/). How about
adding this feature there?
