What is wrong with a URL style of tag where the tag type comes
at the start followed by a colon? The syntax of the rest of the
tag then depends on the tag type.
E.g. in URLs http: and mailto: have different syntaxes.
All we need is a "start of tag" character and a defined syntax for
tag type. We can then add new types with their own syntaxes as
needed and maintain compatibility so that new types can be ignored
by software that doesn't understand them.

Is there going to be a Private tag type?
