<?xml is considered a short-tag or something like that.

No, <? is the short opening tag and is only valid for PHP with the short
open tag enabled in php.ini.

I meant that with short-tags on, <?xml will be considered a short-Tag,
because it begins like one, although it's just plain XML and has nothing to
do with PHP.

<? short open tag for PHP
<?php open tag for PHP
<?xml open tag for XML

And for all three cases the closing tag is ?>.

Wasn't there a thread on PHP-DEV about the PHP-parser mistaking <?xml for a
short-Tag (for <?xml would be valid PHP like <?echo $var?>).

Got my point?

No, there was a discussion if we should disable the short open tag (<?) in
php.ini by default. But that would break the most PHP scripts. But anyway
you should use the always allowed long open tag for portable code and the
benefit of it would be, you can mix PHP with XML. Another point is, if you
move your scripts to a ISP who have disabled short open tags, your scripts
wouldn't work anymore. The normal open tag was discussed in 1997 and was
choosen with XML in mind.

If you enable it and use it, does it work with (otherwise) valid
xhtml?

Has using <?[space] instead of just <? as the short tag been discussed?

It's my understanding that whitespace is ignored. I could be wrong here,
though.
