XLink query syntax

In section 2: locator syntax of the XLink working draft version 1.0
(3/3/98), the use of queries in URI's is discussed as follows:
"...information providers and authors of server software are urged to
use queries as follows: [4] Query ::= 'XML-XPTR=' (XPointer | Name)".
In later documents, it is specified - with no mention of special query
syntax - that "the value of the href attribute must be a  URI reference
as defined in IETF RFC 2396".  Can I use an URI reference that includes
a query in the value of an href attribute just as is?

Thanks for the input,
Julie
