Julian,
Everything sounds fine, some questions inline.

I haven't seen any other draft do this, so I'm unsure of where should  
this go. Abstract? uri-review sounds fine. Too bad the place is a  
spam haven: http://www.ietf.org/mail-archive/web/uri-review

 From RFC
segment       = *pchar
pchar         = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"
sub-delims  = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," /  
";" / "="
gen-delims  = ":" / "/" / "?" / "#" / "[" / "]" / "@"

In practice this means no gen-delims except ":" or "@". The largest  
list of abouts I could find was <http://www.rigaut.com/benoit/CERN/ 
about/>, followed by the more recent <http://en.wikipedia.org/wiki/ 
About_protocol> …Which both contain about URIs with "?". Crap.

How about this:

abouturi = segment [ "?" query ]
query       = *( pchar / "/" / "?" )

Can anyone confirm a use of fragments? Anything else horribly wrong?

tag URI (RFC4151) says "In the interests of tractability to humans,  
tags SHOULD NOT be minted with percent-encoded parts.  However, the  
tag syntax does allow percent-encoded characters in the "pchar"  
elements". Will that do?
