XTCE13 — ArgumentType References Mixed with ParameterTypes in Key

The name constraint for ArgumentType elements enforces uniqueness with ParameterType elements that appear in the CommandMetaData.

<key name="argumentTypeNameKey">
<annotation>
<documentation xml:lang="en">This key ensures a unique argument type name at the system level.</documentation>
</annotation>
<selector xpath="xtce:CommandMetaData/xtce:ArgumentTypeSet/|xtce:CommandMetaData/xtce:ParameterTypeSet/"/>
<field xpath="@name"/>
</key>

This does not make sense because "argumentTypeRef" is distinct from "parameterTypeRef" in all cases.
