Reagle Notice of "Found" Patent Claim
"... To give users the most power and flexibility, a standard object that has the capability to embed objects is used. To allow users even more flexibility, a standard object tracking mechanism is used that allow users to distribute multiple encrypted embedded objects to other individuals in a single encrypted object. By effecting compartmentalization of every object by label attributes and algorithm attributes, multi-level multimedia security is achieved."
Leon Hu Element-wise encryption of XML documents
.. A secure accounting and operational method, whereby process elements are provided to a process, selected process elements are manipulated, a scheduled condition of the process is sampled at a predetermined point in the process, and the process sample is encrypted to provide an encrypted output. As a result, an authorized recipient has a high level of confidence in the reliability of the scheduled condition samples due to the integrity provided by the encryption process.

How to disclose patent claims

"Members disclose patent and other IPR claims by sending email to the publicly archived WG list <xml-encryption@w3.org> (archive) and the archived patent issues list (that is readable by W3C Members and the W3C team) <patent-issues@w3.org> (archive). Members must disclose all IPR claims to this mailing list but they may also copy other recipients."
