Note: in all of the following, when I refer to "XQuery" I mean the latest version of XQuery. Ditto for XQuery Update.
[True or False] XQuery is a superset of XPath. That is, the XQuery language consists of all the stuff in XPath plus more.
Eek! I didn't specify the version of XPath.
[True or False] XQuery is a superset of XPath 1.0
[True or False] XQuery is a superset of XPath 2.0
[True or False] XQuery is a superset of XPath 3.0
[True or False] XQuery is a superset of XPath 3.1
[True or False] XQuery Update is a superset of XQuery.
XQuery 3.1 is a superset of XPath 3.1. Or, more generally, for a given version of XQuery, it is a superset of the same version of XPath.
XQuery Update extends XQuery. XQuery Update remains at version 3.0 and has not been updated to account for XQuery 3.1's support for maps and arrays.
