* Clixon XML XPATH 1.0 according to https://www.w3.org/TR/xpath-10
*
* Note on xcur parameter to most xpath functions:
* The W3 standard defines the document root / element as the top-level.
* In the clixon xpath API, the document root is defined as the top of the xml tree.
* The xcur argument of xpath_first and others is the "current" xml node (xcur) which can
* be any node in that tree, not necessarily the document root.
* This is convenient if you want to use relative xpaths from any location in the tree (eg ../../foo/bar).
* It may be confusing if you expect xcur to be the root node.
*
* Some notes on namespace extensions in Netconf/Yang
* 1) The xpath is not "namespace-aware" in the sense that if you look for a path, eg
* "n:a/n:b", those must match the XML, so they need to match prefixes AND name in the xml
