informaltable.properties — Properties associated with the block surrounding an informaltable
<xsl:attribute-set name="informaltable.properties" use-attribute-sets="informal.object.properties"></xsl:attribute-set>
Block styling properties for informaltables. This parameter should really
have been called informaltable.block.properties or something
like that, but we’re leaving it to avoid backwards-compatibility
problems.
See also table.table.properties.
