plain text for HTML and XHTML. The attached patch
generates acronym and abbr elements, respectively. If
a DocBook acronym element contains a moreinfo

Mozilla, IE, and Opera display a tooltip for elements
with a title attribute. Mozilla's default stylesheet
also displays a dotted line under acronym or abbr
elements with a title attribute.
These elements were introduced in HTML 4.0. If HTML
generation is supposed to be compatible with 3.2, this
can still be generated for XHTML.
