Well, the best way to define URL.revokeObjectURL(blobURL) seemed to be in terms of parsing to extract identifier (scheme data) and then delete the entry corresponding to identifier.

But youíre absolutely right that URL.create* methods shouldnít have a dependency on the basic URL parser, and so Iíve redefined those methods along the lines you say above (namely, defining identifier creation, and then Blob URL creation).

Thatís http://dev.w3.org/2006/webapi/FileAPI/#creating-revoking in todayís editorís draft.

(So *now* maybe the path is clear for Fetch with Blobs.)
