 Nicola, I'm a Web services developer and also a newcomer in semantic 
web, AI and services composition technology. I think experts in this ML 
will answer your question in detail. So please ask you and experts a 
question from a different point of view.

 I think AI  has achieved great success in planning. But it looks like 
practical use of AI planning is not spread as a method  for composing 
program or component. (Sorry if just a shortage of my knowledge)
Experts in Semantic Web Services ML look like conclude that AI planning 
will be useful  for composing web services.

 Please teach me what are the characteristics  of web services which  
practically enable  AI planning to compose a service process, though it 
is fairy difficult to compose programs or components to achieve a 
requirement.
 
 In my humble opinion, 
  1.  higher abstraction of the functionality of service than primitive 
codes or components.
  2. useful standards are fixed like XML, SOAP, WSDL,RDF..., though 
previous program language are components are both proprietary.
  3. 'just' increasing actual requirements for dynamic service composing 
in the intra/internet, which are motivated from a decentralized  
services environment. There was no need for run-time composition and was 
just a need for design-time composition.
  
  I think "1" is the most important characteristic.
 
 Thanks for your opinion.
 
 Regards,
