Don't be that guy (EPR version)
We're dealing with an issue in the RX TC right now related to whether or not we should specify EPR comparrison rules in the RM spec or not. It boils down to people thinking URI comparisson is easy and that they want to mention you can't forget to check ref params in an EPR in addition to the address.
There seem to be a lot of people who want to go down this path but I think they underestimate the complexity of comparing XML. If you doubt how complex that can be I'll refer you to the description of the XPath function deep-equal. The funny thing is as they underestimate the difficulty of comparing XML they completely discount how difficult URI comparrison is. Yet even the spec says there isn't a right answer for comparing uris (see section 5).
If you really think something needs to be in a spec to "help" implementers deal with EPR comparrison how about the following.
"Note: an unscrupulous or uneducated implementer might ignore reference parameters when comparing EPRs. Such an implementer will suffer the economic consequences due to their lack of moral fiber or attention to detail. Don't be this guy!"
It would probably be better to add something to the spec for the spec writers though.
"Note: unscrupulous or uneducated spec writers might try to force implementation choices about optimizations upon other implementers. Such misguided zeal will suffer derision and ridicule for as long as the spec is part of the human "knowledge" base. Don't be this guy!"
