Furthermore, there's RFC 2731 ("Encoding Dublin Core Metadata in HTML"), 
dated 1999, which used the same syntax, but did not require a profile 
attribute. RFC 2731 never was updated, so people implementing it may not 
be aware that DC has essentially obsoleted this spec (this has happened 
to me, so I posted at least an erratum pointing this out, see 

I understand that people will point out that this is evidence that 
@profile isn't needed in practice. On the other hand I would argue that 
a specification that failed to use @profile has been fixed, but that 
process of fixing it failed to make sure people know about it.
