Best practice for handling URI components containing slashes?

[Aron Roberts]

  What is the best practice, vis a vis Restlet's use of URI 
Templates, in handling a URI component that itself includes forward 
slashes?

  Reason for asking: the globally unique identifiers of data items in 
Google's GData world - to which we wish to refer in a RESTful service 
- are themselves URIs, as described in this Google Groups posting:
