Major Description
As per 3.6.2 Structure diagram "name" is mandatory for tModel. Also name should be non-empty - I'm coming with this conclusion from "While the tModel has exactly one non-empty name ..." in 3.6.3 Documentation.
Currently it is possible to save tModel with empty name:
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
<Body>
<save_tModel xmlns="urn:uddi-org:api_v3">
<authInfo>authtoken:f564f3db-f690-414f-97f9-71a410905758</authInfo>
<tModel tModelKey="">
<name/>
</tModel>
</save_tModel>
</Body>
</Envelope>
This could be fixed in ValidatePublish.java - public void validateTModel
from "if (tModel.getName() == null)" to "if (tModel.getName() == null || tModel.getName().getValue().length() == 0)"
