>> PWG 5100.5 is an extension to IPP/1.1 that defines the Document object, the document-attributes-tag (group) value, and the amended semantics for the Send-Document and Send-URI operations. None of that was part of the core IPP/1.1 (which is what RFC 8011 defines) and we've historically been conservative about requiring support for the Document object extension - right now only IPP/2.2 and IPP INFRA require it and most implementations only support a single document per job anyways...<br>

<br>
</span>We also have the Subscription object and its associated attribute group that can be included in Job Creation operations but which we don't say anything about (beyond a reference in the introduction)...<br>
<br>
I think the last thing we want to do is One Spec to Rule Them Allâ„¢. And honestly I don't think that mentioning other attribute groups without providing any details will be all that useful, especially for something as complicated as the Document object extension.<br>
