Hi Bridger, If it’s an option for you to create (possibly intermediate) database for your documents, db:node-id will certainly be the best choice to get unique IDs.

Yeah, the spec says the value can be used to locate a node, but there doesn’t seem to be a htap() function to go from path to node. So, since XQuery lacks xsl:key :), i build a map of generate-id() values to nodes. But if you need to use it between database queries, yes, attributes. -- Liam Quin: Delightful Computing - Training and Consultancy in XSLT / XML Markup / Typography / CSS / Accessibility / and more...
