Good point, I hadn't considered that there might be a limitation there. From a 
quick google it seems the limit is around 65536 for the default format. Of 
course, one could always extend this by packing zip files in the zip files 
(the file size limit seems to be in the terabyte order, not something you'd 
ship over the Web anyway)...

It's possible, for one use case: When the name is a URI, and that URI is 
identical to the URI of the source document, but even then there might still 
be problems (think signatures and provenance).
