When we discussed this in the group, we thought that the W3C would want us to do something like this to guarantee that names were unique and unambiguous (and at least by using URIs we don't have to go through the bureaucratic hassle of adding names to a registry somewhere.)  The spec does allow platforms to define short-form names in addition to the URIs, so that it's legal to support <send type='scxml'.../>, but you must also support the full url form.  So your platform could have an entry <processor name="scxml".../>, but it must also support the full URL syntax.  Since that's what's mandatory, I think that the test has to use it.

My solution is to have canonical names and aliases for invokers and ioprocessors. I just assign all those names to _ioprocessors. You cannot count them anymore to get the number of ioprocessors available, but then again that is not required as per draft.

Thank you.
