W3C published the Media Fragment URI document as a proposed recommendation
The Media Fragments Working Group has published a Proposed Recommendation of Media Fragments URI 1.0 (basic). This document specifies the syntax for constructing media fragment URIs and explains how to handle them when used over the HTTP protocol. The syntax is based on the specification of particular name-value pairs that can be used in URI fragment and URI query requests to restrict a media resource to a certain fragment. The Media Fragment WG has no authority to update registries of all targeted media types. They recommend media type owners to harmonize their existing schemes with the ones proposed in this document and update or add the fragment semantics specification to their media type registration. Comments are welcome through 26 April.
