If I understand this correctly (if not correct me), the attributes are not needed in order to identify the services. The services have these attributed juts as web documents have titles and expiry dates. If this is the case, then under no circumstances should any information other than those needed to identify an object be included in the URL. If the information *is* needed to identify the object, then it must (clearly) be included in the URL. >The discussion makes it clear that attributes can be used >quite effectively in URLs, but only discusses single valued >attributes. I assume we are all happy with a single value being a list with some allowed delimiter.
