Dear Taverna-Team,

As you may know Heliophysics is using the VOTable format to exchange 
data - so do we in HELIO. Our standard wsdl returns therefore structures 
of the type VOTable, as defined by their standardisation organisation 
IVOA. Trying to import these web services (e.g. 
http://msslxw.mssl.ucl.ac.uk:8080/helio-ics/HelioService?wsdl) results 
in a parsing exception:

java.io.IOException: The definition of 
{http://www.ivoa.net/xml/VOTable/v1.1}OPTION results in a loop.

It is true that there is a loop structure, but nevertheless I believe it 
is a valid definition.
Our temporary solution to this problem is to define a Taverna-friendly 
wsdl which returns VOTable 'xs:any'.

Is there any chance that Taverna will be able to parse wsdl files with 
loop structures in the future? Or do you have any other suggestion to 
solve that problem?

I know that many other tools have problems with these kinds of loop 
structures as well.

Best regards,
Anja
