Proposal: External Protocol Handling

Hi all,



I've been working on a draft specification for a creating a dedicated cross-browser external protocol launching standard based on the behavior of msLaunchUri in Internet Explorer.



The draft is here: http://bengjohnson.github.io/ExternalProtocolSpecification.html



I'm looking for feedback from the web app group members on:



*         What major concerns to you have with the overall approach?

o   Do you feel there are insufficient motivating factors for a change to be made?

o   Are there unstated concerns missing from the document?

*         What level of detail are you expecting for a complete proposal?

*         Should it be better aligned with web-based protocol handling? If so, how?

*         And of course, any particular issues with the document in its current form.



Thanks,

Ben
