There seems to be an inconsistency in where four table attributes are available in DB5. The attributes floatstyle, tabstyle, pgwide, and orient are available on table (both CALS and HTML) and informaltable (CALS), but not informaltable (HTML). I think they should be added to informaltable (HTML). I know these are not HTML table attributes, but informaltable (HTML) is not an HTML element, it is a DocBook element that supports the use of HTML element names in its descendants. If we are going to support those four attributes on table (HTML), then we should also support them on informaltable (HTML).
