When using this with HTML we don't link to #line50, or #paragraph3, or 
#section9, we link to an anchor in the document itself. We do this to 
avoid tying the link to a specific representation of the resource, and 
to allow the document to change to a certain extent without breaking the 

I don't know of a video container format that allows named anchors to be 
specified, though.

The interpretation of fragment identifiers on video is a bit out of 
scope for an HTML specification regardless of whether it's specified as 
time or a bookmark. If someone invents a video format that allows named 
anchors, they can write in their own specification how fragment 
identifiers are to be interpreted. It's none of HTML's business.
