How about this for an update to section 4:

4  Get-User-Printer-Attributes Operation
The Get-User-Printer-Attributes operation is semantically analogous to the Get-Printer-Attributes operation [RFC8011] but the response can be filtered based on the most authenticated user. The authenticated user (see section 9.3 of [RFC8011]) performing this operation MUST be either a User permitted to create Print Jobs or an Operator or Administrator of the Printer.  Otherwise, the Printer MUST reject the operation and return 'client-error-forbidden', 'client-error-not-authenticated', or 'client-error-not-authorized' as appropriate.

The Client MUST be prepared to handle an HTTP authentication challenge in response to a Get-User-Printer-Attributes operation request. If the Client initiates the Get-User-Printer-Attributes operation over a non-TLS connection, the Client MUST be prepared to receive an HTTP 426 response to upgrade the connection to TLS [RFC2817]. See [RFC8010] and [RFC8011] for authentication methods that require a secure channel.

A Printer MUST support all the same operation attributes for a Get-User-Printer-Attributes operation that it supports with a Get-Printer-Attributes operation, including those used by a Client to request a filtered response: “document-format” [RFC8011]; “first-index” [PWG5100.13]; “limit” [PWG5100.13]; and any of the attributes named by “printer-get-attributes-supported” [PWG5100.13].

Prehaps rewording to “  … Attributes operation [RFC8011] except that the response can be filtered based on the most authenticated user and to effect this, the operation can prompt a sequence to authenticate the user.” Or something like that.

The ‘odt’ format is not compatible with , at least, my version of MS Word to the extent that opening it in MS Word produces a incorrectly displayed document subject to extensive editorial comments. The Process states “ Internal working versions of PWG documents should be available in an agreed upon, widely available word processing format, to provide for collaboration between document editors and contributors. For example, Microsoft WORD and HTML are common
