RE: [xri] Service element question

["Drummond Reed" <drummond.reed@cordance.net>]

I've thought about that too, Victor. I honestly don't know a specific use
case for needing Service priority but since you can have more than one
Service match the service endpoint selection criteria, you may then need
priority to distinguish them.

For example, you want to design a set of services that by one selection
criteria (Type, for instance) are all unique but by another (Path, for
instance) they might all be selected. In this case, you might want to use
priority to distinguish them.

Subject: [xri] Service element question

The latest editor drafts of Res 2.0 WD10 state that the Service element 
of an XRD has a priority attribute, because "there can be more than one 
instance of a particular service type for redundancy".

It's a small point, but since a Service element distinguished by a 
particular combination of Type|MediaType|Path elements can have n-URL 
elements with priority attributes, what is the case where you would 
want instead to have more than one Service element with the same 
Type|MediaType|Path elements?
