Implements org.apache.xerces.impl.xs.models.XSCMValidator.checkUniqueParticleAttribution.

check whether this content violates UPA constraint.

Parameters
subGroupHandler:SubstitutionGroupHandler

the substitution group handler

Returns:boolean

Returns the name of the term (element or wildcard) for the given identifier.

Parameters
termId:int

identifier for the element declaration or wildcard

Returns:String
