I have some comments that I hope may be useful.

First, I think that your statement that we have only 2 major XSLT 2.0 
processors is incorrect. I fail to see how Gestalt is less major than 
Altova.

In gestalt, the collection function currently only accepts a file: URI which 
must be a legitimate file URI
pointing to a directory. All files in this directory that sucessfully parse 
as xml create a document node in the directory.


Secondly, it would be better in your example to change the template with 
match="/" to one with name="initial". Asking the user to supply a dummy 
document is senseless.

Thirdly, I think it is very bad of Saxon to have two completely different 
meaning for the file URI scheme in the collection function (I refer to the 
catalog and the wild-card forms, both of which have a completely different 
meaning).

The catalog form is at least a legalfile URI, although it's meaning is so 
unintuitive that I think a different (custom) URI scheme should be used.

The form with wildcards is just not legal according to RFC 1738.

So I cannot recommend standardizing on Saxon's usage here.
