Not so.
Within a representation with a well defined base URI of
http://a/b/c/d;p?q
a relative reference is transformed to its target URI as
follows.
...
"" = "http://a/b/c/d;p?q"
-- 5.4 and 5.4.1, Reference Resolution Examples, RFC 3986
However, I do agree that it's best avoided in production as not all user
agents agree. For example, and as David said, IE will treat empty URIs
in links as "./", though it will act properly for FORM action attributes
with empty values.
