Hi Marc,
I was considering URIs in a more general context than just HTML forms and
the application/x-www-form-urlencoded media type. Looking at the latest URI
spec [1], I see little constraint on what can make a query part.
So, it would be nice to have a convention similar to Matrix parameters while
keeping the ability to explicitly specify the Boolean values if required.
Best regards,
Jerome
