* XPath parser: fixing lexical issues cornercases

Browse source 
* Some complexities in Section 3.7 Lexical Structure of XPath 1.0 spec
  * There used to be some cornercases where function-names could not be used as nodes
  * For example, `node()` is a nodetest, so `/node/` caused an error.
  * In the grammar these include: axisnames,  nodetests, functionnames
  * The NCNames vs functionnames is now impölemented according to the lexical structure section
