- public class XSSimpleCM
- extends java.lang.Object
- implements XSCMValidator
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.
