Please add "named as" attribute to a "part of" relationship between works. A name of the attribute may be different, but it means how a part is named in a context of a parent. The attribute shall be optional. If the attribute is populated, it shall be used to show the name of a work when it is displayed as a part in a context of the parent work.

The particular use case is this:

• There is a parent work which contains vocal as well as purely instrumental parts.
• There is a translation of the parent work into a different language.
• Vocal parts are different for the original and translated work (relationship "translated version of"). Vocal parts also have different work names, that is names in the appropriate language.
• Purely instrumental parts are shared between translated works (there is no translation of a purely instrumental part, since it has no lyrics). Still, a purely instrumental part may be referenced by a different name in a context of a translated work.

Example: the same instrumental part shall be named "March" in a context of an English work, but "Marsch" in a context of a German translation. It is the same work, but it has several parent works, and shall be referenced by different names from different parents.

This is similar to an attribute "credited as" for a relationship between a recording and a performer. Each performer has a canonical name, but he may be referenced by a different name in a context of a particular recording.
