HDATA — Minor deletion or rewrite to PUT operation wording

Context:
6.5 baseURL/sectionpath/documentname
6.5.2 PUT

The text "If the request is successful, the new section document MUST show up in the document feed for the section" is not applicable for a document update since it's not a new document but an update.

This is text verbatim from section 6.4.2.2 [Add new document].

The text could be deleted or reworded to something like this:

"If the request is successful, the updated section document MUST [continue to] show up in the document feed for the section".

Changed as suggested by submitter. Note that this applied to the new section 6.5.3, since it was exchanged with 6.5.2.
