Subject: 48-Hour Call for Consensus (CfC): POE Use Cases and Requirements


This is a Call for Consensus (CfC) to the Accessible Platform Architectures (APA) Working Group on a proposed APA comment to the Permissions & Obligations Expression (POE) Working Group, concerning their now stable Use Cases and Requirements document


The Abstract of this POE document states:

"This document includes a set of use cases and requirements, compiled by the Permissions & Obligations Expression (POE) Working Group, that motivate the expression of statements about digital content usage. All use cases provide realistic examples describing how people and organisations may (or want to be able to) specify statements about digital content usage. The requirements derived from these use cases will be used to guide the development of the POE WG recommendation deliverables for the Information Model, Vocabulary, and Encodings."

**Suggested Comment**

The Accessible Platform Architectures (APA) Working Group has reviewed the POE's Use Cases and Requirements document at:


We were unable to find  the following accessibility use case in this document and request it be added to this document and appropriately addressed in all resulting normative specifications.

Historically, similar schemes have been used to deny content access to assistive technology users, e.g. Microsoft Reader, Adobe PDF (which to this day includes a checkbox for denying AT access).

POE  should clearly state its intention to include alternate access technologies among it's licensed uses, and require implementing technologies to insure they will not be blocked, neither intentionally nor incidentally.


This CfC is now open for objection, comment, as well as statements of support via email. Silence will be interpreted as support, though messages of support are certainly welcome.

If you object to this proposed action, or have comments concerning this proposal, please respond by replying on list to this message no later than 23:59 (Midnight) Boston Time, Sunday 17 February.

NOTE: This Call for Consensus is being conducted in accordance with the APA Decision Policy published at:
