special characters in gadget specification

[Martin Höller]

Hi!

Whenever I use special characters (umlauts) in gadget specifications,
shindig gives me this:

WARNING [AbstractSpecFactory] Beim Aktualisieren von
http://10.168.162.10:8380/emcs/gadget/specs/quickStart.xml ist ein Fehler
aufgetreten. Es wird stattdessen eine zwischengespeicherte Version
verwendet.

Which means an error occurred on loading specification, a cached version
will be used.

This error comes from AbstractSpecFactory line 234. The exception (that
is not shown in the logs btw.) is this:

org.apache.shindig.gadgets.spec.SpecParserException:
  org.apache.shindig.common.xml.XmlException:
  The entity "ouml" was referenced, but not declared. 

The reason for the error seems to be the use of an umlaut ("ö" and "ü")
in the title of the gadget:

  <ModulePrefs title="persönliches Menü">

Using "&uuml;", "&#252;" or "&amp;uuml;" doesn't bring me any further.

I couldn't find anything useful searching the net, so my question is: is
this a restriction of the specification or a bug in shindig (or the used
XML parser).

regards,
- martin
