>This is a new set of XML combinators for Xtract, not standard,
   but based on the standard set in <A HREF="Text-Xml-Haxml-Combinators.html"
>Text.Xml.Haxml.Combinators</A
>.
   The main difference is that the Content Filter type becomes a
   Double Filter.  A Double Filter always takes the whole document
   as an extra argument, so you can start to traverse it again from
   any inner location within the document tree.
</P
><P
>The new combinators definitions are derived from the old ones.
   New names are derived from the old by surrounding with the letter <TT
>o</TT
>,
   or by doubling the operator symbols.
