java.lang.Object | +--org.apache.xerces.impl.xs.models.XSSimpleCM
XSSimpleCM is a derivative of the abstract content model base class that handles a small set of simple content models that are just way overkill to give the DFA treatment.
This class handles the following scenarios:
These all involve a unary operation with one element type, or a binary operation with two elements. These are very simple and can be checked in a simple way without a DFA and without the overhead of setting up a DFA for such a simple check. This model validated on the way in.
