I'm surprised by...

"If the XML document specifies an <?access-control?> processing instruction,
access to the data is allowed based on the following

Last time a processing instruction was used in a W3C spec,
it was allowed only after considerable debate...

"The use of XML processing instructions in this specification should not be
taken as a precedent. The W3C does not anticipate recommending the use of
processing instructions in any future specification."

I suggest using a namespace-qualified element or attribute instead.
