- patterns are missing - here's my attempt to rewrite [5.2] (of the
spec) to make it a bit clearer (and not too inaccurate) - feel free to
continue rewriting it -

PATTERN: A pattern is a kind of EXPRESSION. An expression that is also a
pattern always evaluates to a node-set.
  The main use of patterns is to identify which nodes a template can
apply to, viz. it can apply to any node that matches the pattern
specified in its select attribute. In a pattern, | indicates
alternatives; a node matches a pattern with one or more | separated
alternatives if it matches any one of the alternatives. Each alternative
is a sequence of STEPs separated by / or //; it is matched from right to
left: a node matches an alternative only if the rightmost step matches
the node and a suitable element matches each of the other steps; if the
separator is / then only the parent is a suitable element; if the
separator is //, then any ancestor is a suitable element.
  Patterns are also used for numbering and for declaring keys.
