In as much as XML doesn't make the distinction, then this change looks fine. ` -Saveen -----Original Message----- From: Jim Davis [mailto:jdavis@parc.xerox.com] Sent: Monday, September 14, 1998 9:50 AM To: www-webdav-dasl@w3.org Subject: no empty strings in DAV section 5.5.3 says "Empty strings (zero length strings) are not NULL values." I think this should be "Empty property values are not NULL values." because 'empty string' is not a DAV concept, but 'empty value' is. Many DAV properties may be empty (e.g. resourcetype, lockdiscovery). Nowhere does DAV speak of empty 'strings'. Moreoever, in XML (which DAV uses) there does not seem to be any way to make this distinction. That is, the XML <foo></foo> is just empty. It does not contain a zero a length string, it just does not contain anything. So I do not see how a property in DAV could ever come to contain an 'empty string' Any objection to changing the language? ------------------------------------ http://www.parc.xerox.com/jdavis/ 650-812-4301
