J. Braham Cabinet as Collaborative work

[Jaquick]

I want to add a file for Tell Me, Sweet Bird by John Moorehead, one of his contributions to the opera The Cabinet. This work sits on the John Braham page (one of the collaborators). I've added collaborator code to list all the collaborators (from Moorehead article in New Grove), and "|Page type=Collaboration" to the work page. But I'm at a loss to figure how to add the new excerpt, since a collaborative work doesn't show up on Moorehead's page. Is here code I'm missing? I couldn't find any documentation for collaborative works onsite.

I've added the necessary code. At the end of the page you needed to use the CollabCat template so that the work page would show up under the collaborations tab on each composer's category.
