Performance is the biggest consideration in the design of SAX2DTM2. To make the code most efficient, the incremental support is dropped in SAX2DTM2, which means that you should not use it in incremental situation. To reduce the overhead of pulling data from the DTM model, a few core interfaces in SAX2DTM2 have direct access to the internal arrays of the SuballocatedIntVectors.
The design of SAX2DTM2 may limit its extensibilty. If you have a reason to extend the SAX2DTM model, please extend from SAX2DTM instead of this class.
%MK% The code in this class is critical to the XSLTC_DTM performance. Be very careful when making changes here!
