> An XPath query (via QueryManager) like '//element(*, nt:nodeType)[@jcr:isMixin=@jcr:hasOrderableChildNodes]' ought to find at least some nodes (e.g., /jcr:system/jcr:nodeTypes/nt:version).  However, this query results in no matches.  Oddly, changing the comparison from = to != still results in no matches.
> It appears that it is not possible to test for equality of the values of two attributes on the same node (I haven't tested two attributes from different nodes).
> The use case that led to this discovery was one in which I wanted to find all nodes (cards) in an address book for which the first name attribute matches the last name attribute.  Any workarounds would be much appreciated.
