URI characters: [] formerly unwise, now ok?

The feed validator [1] just gave an error because I had the following
as the value of an rdf:resource attribute (in extended RSS 1.0) :

http://www.w3.org/2005/Talks/1110-iswc-tbl/#[18]

(Sorry, forgot to snapshot the error message before I fixed it)

I just did a quick skim, RFC 2396 considers '[' and ']' as "unwise",
RFC 3986 has these as reserved (gen-delims). I think because these
characters aren't reserved for any specific purpose in the http:
scheme, they're ok here.

The source of the characters is the script that powers the slideshow [2]:

uri = uri + "#[" + (slidenum+1) + "]";

Cheers,
Danny.
