XPointer WD 20010108 - location-set "error"? from AndrewWatt2000@aol.com on 2001-01-18 (www-xml-linking-comments@w3.org from January to March 2001) (original) (raw)

It seems to me that there is an error in the 8th January 2001 XPointer WD.

It states as a definition of "location-set": "An ordered list of locations, such as produced by an XPointer expression. This corresponds to the node-set that is produced by XPath expressions, except for the generalization to include points and ranges."

However the November 1999 XPath Recommendation defines a node-set as: "an unordered collection of nodes without duplicates"

Thus there appears, contrary to the XPointer WD, to be a further distinction between an XPointer location-set and an XPath node-set in that the location-set is ordered while an XPath node-set is UNordered.

The alternative interpretation is that if an XPointer location-set is a generalisation of an XPath node-set to include points and ranges then it too is unordered. I couldn't readily find clarification in the XPointer WD.
