           Summary: [UPD] Rename: default namespace for attributes
           Product: XPath / XQuery / XSLFO / XSLT
           Version: Last Call drafts

            Status: NEW
          Severity: normal

The expression

for $a in //@PRICE return
  rename $a as "COST"

is currently defined to treat COST as a name in the default namespace for
elements and types, despite the fact that it is clearly being used as an
attribute name. Presumably the system is supposed to invent a namespace prefix,
since the name clearly cannot be used unprefixed (or is this supposed to lead
to a data model consistency error?) Either way, this seems likely to cause
unwelcome surprises.
