The working group maintains a list of all bug reports that the editors have not yet tried to address; there may also be open bugs in the previous bug tracker.
Implementors should be aware that this specification is not stable. Implementors who are not taking part in the discussions are likely to find the specification changing out from under them in incompatible ways. Vendors interested in implementing this specification before it eventually reaches the Candidate Recommendation stage should join the mailing list mentioned below and take part in the discussions.

This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.

This registry is intended to enhance interoperability among implementations and users of
SourceBuffer objects described in the
Media Source Extensions™(MSE) specification. In particular, this registry provides the means (1) to identify and avoid MIME-type collisions among byte stream formats, and (2) to disclose information about byte stream formats accepted by MSE implementations to promote interoperability.
The registry maintains a mapping between MIME-type/subtype pairs and byte stream format specifications. The byte stream format specifications describe the structure and semantics of byte streams accepted by
SourceBuffer objects created with the associated MIME-type/subtype pair.
This registry is not intended to include any information on whether a byte stream format is encumbered by intellectual property claims. Implementors and users are advised to seek appropriate legal counsel in this matter if they intend to implement or use a specific byte stream format.
SourceBufferwhen handling the byte stream format.
If a registration fails to satisfy a mandatory requirement specified above, then it MAY be removed from the registry (without prejudice).
