Yes, a "list" is synonymous with a "sequence" as well as "ordered
forest".  We are actively trying to align the terminology used in all
the XML Query documents.

No.  The nodes or scalar values in a list/sequence/ordered forest do not
necessarily have any sibling relationship.

Thanks for the suggestion. We choose terms based on study of commonly
used computer-science terms and based on what we believe will be most
intuitive to users.

We appreciate your feedback on the XML Query specifications. Please let
us  know if this response is satisfactory. If not, please respond to
