RE: Amendment to Holdings Schema ................................ .... ..........J.nr. 331-4

I have not a strong opinion about this, but it seems to me that Joe is
right. 
Almost all the fields in the BibPart are optional, so you don't have to
repeat them. So I do not think that it is "very complicated" and I don't
understand why this is a DanZIG profile issue.

Maybe we can ask Rolande what she thinks about this?
