* doc/html/*.html: Finally - found the problem with the
  page generation (XMLPUBFUN not recognized by gtkdoc).
  Re-created the pages using a temporary version of
  include/libxml/*.h.
* testOOMlib.c,include/libxml/encoding.h,
  include/libxml/schemasInternals.h,include/libxml/valid.h,
  include/libxml/xlink.h,include/libxml/xmlwin32version.h,
  include/libxml/xmlwin32version.h.in,
  include/libxml/xpathInternals.h: minor edit of comments
  to help automatic documentation generation
* doc/docdescr.doc: small elaboration
* doc/examples/test1.c,doc/examples/Makefile.am: re-commit
  (messed up on last try)
* xmlreader.c: minor change to clear warning.

Call this routine to speed up XPath computation on static documents.
This stamps all the element nodes with the document order
Like for line information, the order is kept in the element-&gt;content

to be able to differenciate from line numbers.</p><p>

Evaluate a predicate result for the current node.
A PredicateExpr is evaluated by evaluating the Expr and converting
the result to a boolean. If the result is a number, the result will
be converted to true if the number is equal to the position of the
context node in the context node list (as returned by the position
function) and will be converted to false otherwise; if the result
is not a number, then the result will be converted as if by a call
