Subject: For tables with HTML markup elements, added support for dbfo bgcolor PI,
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=95687be9cd94dd58a65cc58d720537fc02cd6468;p=docbook-dsssl

For tables with HTML markup elements, added support for dbfo bgcolor PI,
the attribute-sets named table.properties, informaltable.properties,
table.table.properties, and table.cell.padding.  Also added support
for the templates named table.cell.properties and table.cell.block.properties
so that tabstyles can be implemented.   Also added support for tables
containing only <tr> instead of <tbody> with <tr>.
