I'd mention 'userinfo' in that URI.

RFC3986 has a definition for a 'path-absolute', but this is something which is
concatenated to the 'host'. A 'host' for RFC3986 cannot contain a '/':
host = IP-literal / IPv4address / reg-name
with
reg-name = *( unreserved / pct-encoded / sub-delims )
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
sub-delims = "!" / "$" / "&" / "'" / "(" / ")"
/ "*" / "+" / "," / ";" / "="
I guess you could rework the current definition with something like:
URI = URI-unix / URI-net
URI-net = spice-scheme-net://host:port?param1=value1¶m2=value2...
URI-unix = spice+unix://path-absolute
Or decide that for now, the current definition is good enough ;)
