My experience has been that the issues surrounding web services are not the 
WSDL but resolving other technologies that it uses: i.e. the resolution of 
namespace mapping and schema analysis.

1) It's pretty obvious that namespaces (aka packages, etc) introduce many 
indirection concerns (consider the earlier experiment in erlang with module 

2) The issue with xml schema seems to be the underlying DTD (heavily 
documented to note exceptions) and what is far worse, the use of 

If there was a fully resolved solution in erlang to both xmlns and xsd, 
then I suspect generic web services would not be at all difficult.

(For another take on the subject, Joe Armstrong's UBF contains a strong 
argument for rethinking XML in general).
