I read 'not required to' as 'can't be guaranteed to', therefore I can't
assume there will be data I can use to do an equality of content check
against.

If I design a system that assumes URIs refer to data in order to work, I
have violated the 'not required' rule. You always have to design for the
worst case.

Read it as 'can't assume there is any data referred to' so only the URI text
can be used to establish identity of 2 URIs.

	That is absolutely not true. URIs can refer to data just as URLs
can. URIs
	are not *required* to refer to data, but they can.
