Re: [xsl] ancestor axis order

[David Carlisle <davidc@xxxxxxxxx>]

  with the expression
       ancestor::*[self::define or self::choice][1][self::choice]
  there are no 'nested' predicates, hence its a single step.
  I.e. the step is all in reverse document order.


I'm not sure what you mean by a nested predicate but yes,, it's a single
step because XPath steps are the chunks you get by splitting up an
expression at top level /

/a[a/b/c]/x/y[a or b or c/d]

has three steps
/a[a/b/c]
/x
/y[a or b or c/d]

although of course the sub-expressions such as a/b/c are themseleves
made up of multiple steps.


  Innermost being the node closest to 'ref' element, further away
  from the root.

yes (sorry one place I lapsed iinto ad-hoc terminology rather than
xpath terminology)
