Subject: Re: Issue: empty strings as keys and keyRefs
> I think the simplest solution will be to say that <key> and <keyRef> don't > match empty strings even if the included pattern can match an empty string, "" (the string of length 0) is not the only one. To be precise, "empty string" is a string that consists of #x20,#xD,#xA. Because patterns like <element name="foo"> <choice> <empty/> <key> <data type="string"> </key> </choice> </element> and an instance <foo> &xD; </foo> is still ambiguous. regards, -- Kohsuke KAWAGUCHI +1 650 786 0721 Sun Microsystems kohsuke.kawaguchi@sun.com
