I really don't see how the result-tree-fragment could be accessed from a non-xslt implementations. > out of these, i have seen current() and generate-id() used in schematron > files i have used. generate-id() might be easy current() is a matter of semantic, since it's not part of a stylsheet anymore what semantic would you give ? things like format-number() are a RPITA frankly, I would prefer not to duplicate that horror. maybe a practical approach would be to offer only the few funtions which are easy to duplicate outside an XSLT context.
