i was aware of xml serialization to <hr/>, but xhtml serialization to
<hr /> is recommended for compatibility only. so the xml method is still
the only way to output valid xhtml, since the html method removes the
trailing slash.

but, you are right, my first thought was not entirely right. guess, i
wasn't going the whole way. i wasn't thinking about this little
difference at all.

so there is no "recommended" way. that's what i wanted to know.

is there going to be a xhtml output method?

no. it's not important to my work. when i was converting one of my old
html output stylesheets to output valid xhtml i was wondering if its
possible at all to have the xhtml/html entity references in the output
at all, as it works with html output. i haven't read anything specific
about it, so i was asking myself if there is a standard way.

yes, but in html output the xhtml/html entity references are used for
output. that's why i was thinking about it.

yes it did,
