DOCBOOK-APPS: Callouts in XHTML

[Jason Diamond <jason@injektilo.org>]

Hello.

I'm running into a weird discrepancy using the HTML and XHTML XSL
stylesheets. For both of them, programlisting inside a programlistingco gets
turned into a pre element. With the HTML stylesheets, the callout img
elements are being inserted directly into the pre element. For the XHTML
stylesheets, the pre element is closed, after which the img is inserted, and
then the pre element is opened again. This is causing both Mozilla and IE to
display the callout image at the beginning of the line following the line
it's supposed to be on. It renders fine when using the HTML stylesheets.

I'm trying to track the problem down (assuming this isn't intentional) but
thought I would see if anybody else has ran into this problem and
(hopefully) already discovered the cause or fixed it.

Thanks,
Jason
