- public class XSDFACM
- extends java.lang.Object
- implements XSCMValidator
DFAContentModel is the implementation of XSCMValidator that does
all of the non-trivial element content validation. This class does
the conversion from the regular expression to the DFA that
it then uses in its validation algorithm.

- endContentModel in interface XSCMValidator
- Tags copied from interface: XSCMValidator
- Parameters:
state
- Current state of the content model- Returns:
- true if the last state was a valid final state
