Wikimedia Bugzilla is closed!

Wikimedia has migrated from Bugzilla to Phabricator. Bug reports should be created and updated in Wikimedia Phabricator instead. Please create an account in Phabricator and add your Bugzilla email address to it.
Wikimedia Bugzilla is read-only. If you try to edit or create any bug report in Bugzilla you will be shown an intentional error message.
In order to access the Phabricator task corresponding to a Bugzilla report, just remove "static-" from its URL.
You could still run searches in Bugzilla or access your list of votes but bug reports will obviously not be up-to-date in Bugzilla.

The following example
<pre>
<inputbox>
type=create
break=no
prefix=Forum:Ideen/
preload=Vorlage:Forumkopf/{{PAGENAME}}
buttonlabel=Neues Thema hinzufügen
</inputbox>
</pre>
creates invalid HTML.

The following tag is opened but not closed:
<pre>
<input type='hidden' name="action" value="edit" >
<pre>

Create correct HTML for create boxes.

The appended patch eliminates the problem with open input tag.

Closing tags is mandatory in XHTML as opposed to HTML 4.0.
Mediawiki 1.7.1 creates XHTML output.

Applied to r16157, with several other XHTML fixes.
