Imports
com.sun.tools.rngdatatype.Datatype, .DatatypeBuilder, .DatatypeException, .ValidationContext
Dummy implementation of DatatypeBuilder. This implementation can be used for Datatypes which have no parameters. Any attempt to add parameters will be rejected.

Typical usage would be: 

class MyDatatypeLibrary implements DatatypeLibrary {
    ....
    DatatypeBuilder createDatatypeBuilder( String typeName ) {
        return new ParameterleessDatatypeBuilder(createDatatype(typeName));
    }
    ....
}
