I will give you two:
  - libxml2 preserves entity references in attributes
    values, SAX doesn't allow it but I decided I wanted that feature.
  - libxml2 DOM shares a common subtree on multiple entities references
ask first for entity substitution to avoid them.
Plus a number of reasons which make SAX hard to use in pure C, Megginson
never bothered trying to solve those, SAX is not a C friendly API, it's
also too limited for an editing toolkit like libxml2.

Look at the various entry points in SAX.c related to entities, and
the value of ctxt->inSubset.
