I presume that it is a illegal uri, but my thoughts are that it should
be obvious enough not to be need.
http://www.example.com/country:US/state:MA/city:Boston
would be more correct.

The protocol-identifier is a simple identifier that names a
URI-protocol handler. It is up to the named handler to interpret the
uri-body and return the value of the URI expression. The value of a
URI expression will usually depend on which protocol handler is named.
The URI body must begin with one of these characters:
a-z, A-Z, 0-9, any of ;/?@&+$-_.!~*'().%#\|
After the first character, the URI body consists of characters from
this set, plus "=" and ":".
