I created text for this here <> in a PR against EAT. It’s pretty simple:

5.1.  <file:///Users/lgl/Documents/EAT/eat-drafts/eat/draft-ietf-rats-eat.html#section-5.1>Format of a Profile Document <file:///Users/lgl/Documents/EAT/eat-drafts/eat/draft-ietf-rats-eat.html#name-format-of-a-profile-documen>
A profile document doesn't have to be in any particular format. It may be simple text, something more formal or a combination.
In some cases CDDL may be create that replaces CDDL in this or other document to express some profile requirements. For example, to require the altitude data item in the location claim, CDDL can be written that replicates the location claim with the altitude no longer optional.
