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.

Release Argument and Parameter Type Name Uniqueness

Proposal is to release the uniqueness key from binding CommandMetaData/ParameterTypeSet names with CommandMetaData/ArgumentTypeSet names.

Existing key definition:

<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>

Revised key definition:

<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/*"/>
<field xpath="@name"/>
</key>
