Subject: Modified match="co" template to use its linkends attribute
X-Git-Tag: release/1.79.1~6^2~5880
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=989225b82076bffa069a79483751dd8314edaf7e;p=docbook-dsssl

Modified match="co" template to use its linkends attribute
to form a hotlink to the callout element, forming the
two-ways links as described in
The Definitive Guide.  At this time, only a single linkend
value is supported, since HTML doesn't handle multiply-targeted
links.
