Seeing that independent specs can always add new values, I think its valuable to point to a wiki page with the latest known values. We currently only have the following known types: "navigation", "resource", "mark", "measure". Philippe, do you want to add this to a wiki page? I can update the spec to point to the wiki page.

I think it's reasonable to allow user agents to create experimental PerformanceEntry objects, e.g., GraphicsTiming or other performance metrics. Thoughts on the following text?

4.4 Vendor Extensions

If a vendor-specific proprietary user agent extension is needed to create experimental PerformanceEntry objects, on getting the entryType IDL attribute, vendors MUST return a DOMString that uses the following convention:

[vendorprefix]-[name]

Where,
•[vendorprefix] is a non-capitalized name that identifies the vendor,
•[name] is a non-capitalized name given to the type of interface represent by this PerformanceEntry object,
•and the above names are in ASCII.
