def writeXML(hAttribute)

   # xml for iso classes Multiplicity and MultiplicityRange
   # in 19110 cardinality is expressed as multiplicity, a min/max range
   # Multiplicity is not defined in the documentation, only inferred from the XSD
   # max cardinality -----------------
   # ISO 19110-2 rule
   # ... "If this is an attribute or operation, the default cardinality is 1"
   # there is no hint if this refers to min or max of the range, I chose max
   # I assume this means the attribute can occur only once in the entity
   # I set the internal object mustBeUnique = true as default
   # I assume false would describe something like a repeating tag in an XML file
   # min cardinality -----------------
   # mdJson allows setting flag to allow nulls as attribute values
   # I set this into minimum cardinality
   # issue ---------------------------
   # min cardinality refers to the attribute values
   # max cardinality refers to the attribute instantiation
   # perhaps one of these should not be carried in ISO19110
