Subject: [PATCH] Added support for @xlink:show in the simple.xlink template.
 The "new" and "replace" values are supported (corresponding to values of
 "_blank" and "_top" for the ulink.target parameter). I have assumed that
 @xlink:show should override ulink.target for external URI links. This closes
 bugs #1762023 and #1727498.
