Hm, I'll have to include support for "nillable" in erlsom. I have to confess
that I was not aware of this limitation. It shouldn't be too add, I'll try
to put it into a new release in the near future.

I deleted all occurances of nillable="true" from the WSDL file and tried

I looked at the WSDL you sent me, and I noticed that it contains a number of
<schema> elements. I suppose that this is perfectly legal, but I never
considered it. I'll try to fix this in a next release.

In the mean time, you could try to reduce the number of <schema> elements to
1, using <include> to include the additional schema's into this 1 remaining
schema. This should work (I didn't try it...), and the effect should be the
same.


Also, I tried the test function is yaws_soap_lib:qtest() and it failed. Any
> help/explenation is appreciated.


I'm sorry, but I was not able to reproduce the error you sent me. I did find
another error, related to the use of ibrowse. This can be fixed by
commenting out lines 273-275 in the file yaws_soap_lib.erl.
