This matches what I understand.  Now some comments just to make
sure we're all on the same page.

TR9401 says:
  The BASE keyword specifies that relative storage object identifiers (SOIs)
  in the right hand side of entries following this entry in the current
  catalog entry file should be resolved relative to the storage object
  identifier of this BASE entry.

That would apply equally to the SOI in CATALOG and DELEGATE entries.
Therefore, I assume we plan to do likewise.  Using Norm's example,
that means that, within the group with xml:base="absURI", both the 
delegated-to catalog and the public id's uri are relative to absURI.
I think this is as it should be, but I wanted to point it out to make
sure we all have the same understanding.

I'd also point out that, though Norm's example used a value of "absURI"
for xml:base, the value of xml:base needn't be an absolute URI.
