Subject: Re: [docbook-apps] [BUG] <para><informaltable> generates spurious <p> blocks
Hi Kevin, Regarding the empty p elements, what you are seeing is the result of the $html.cleanup parameter triggering the unwrap.p mode in the HTML stylesheets (specifically, in xhtml/html-rtf.xsl). If you check any HTML DTD, you'll find that table (or any other block) is not a permitted child of p. So when $html.cleanup = 1, the stylesheet recursively passes through the content of the p to close the p before any such block as table, outputs the block, and restarts a new p. The p elements before and after are not strictly empty, they each contain a single text node with the whitespace (which is preserved inside a mixed content element like para). In general, you can expect better results by not nesting block elements inside para elements in DocBook, which avoids problems like this. Regarding the missing table elements, I'm afraid you have a hybrid table in your document. It doesn't have a tgroup, so it isn't a CALS table, but it doesn't have a tr, so it isn't an HTML table either. Unfortunately, DTD syntax doesn't permit flagging that combination as invalid because there is only one tbody declaration for both CALS and HTML tables, and DTDs can have only one content model per element. The DocBook 5 RelaxNG schema can flag that table as invalid. So your table should work if you add the tgroup element.
