Isn't there? Let me look...

Oh. you're quite right.

I suppose the relevant section is actually
  3.2.1. Representation types and fragment identifier semantics
  http://www.w3.org/2001/tag/2004/webarch-20041021/#media-type-fragid
Is that where we started? No... your original comment
refers only to section 2.6. Perhaps the text in 3.2.1 helps?
It could perhaps be clearer, but we tried hard and this is the
best we came up with. We've considered diagrams and such, but
haven't managed to produce them.

You're using "secondary resource" as a class. Were we not sufficiently
clear that it's not a class of resources, but that primary/secondary
is a relationship between resources?

Whether a resource has a representation is orthogonal to whether
it is primary or secondary.
