Re: The Road to 3.0

Hey Dave,
	I should have read this mail before replying!  It was certainly the 
case in the past the some of the platforms that xerces supported did 
not have decent STL support. Has this now changed? Dean knew all the 
issues if I recall correctly and does sometimes lurk on the list. Are 
you out there Dean?

Lots of cool ideas there.  I'm with Alby though in being reticent

drawing in STL-based code at this juncture.  I could be wrong about
this,
but I seem to recall something about Xalan-C having relatively 
recently
gone through a painful change away from STL for the sake of 
portability.
Actually, the Xalan-C code was quite portable with the standard 
library.
However, trying to implement pluggable memory management like Xerces-C 
did
is not possible with the standard library, so we wrote some container
classes that are very much like the standard ones (vector, list, 
deque),
but which support Xerces-C's MemoryManager class.  In fact, it went
further than I wanted it to, and they actually require an instance of a
MemoryManager to operate.

It might be interesting for Xerces-C to adopt those classes, but they 
do
still need some work, both in design, and performance.  And, although 
they
have been relatively bug free within the context of how we use them in
Xalan-C, I'm not willing to guarantee that there aren't problems 
lurking
therein.
