Yes: what I was saying is that the SAXON implementation of generate-id()
conforms to the spec but also offers some additional guarantees. These
include:
- it will always generate the same id's for the same source document
- the id's will be collated in document order
- the id for a node is a leading substring of the id for its descendant
nodes.

Of course, if you choose to exploit these features you are sacrificing
portability.
