I am merely stating a fact of my expertise in implementation. There is a difference in programming between the concepts, and that fact should be able to be modeled in data files. It's why SQL databases have some columns that allow NULL, for instance. A NULL column in a database could mean something different than a zero length string, depending on the business rules at hand. -----Original Message----- From: Boris Zbarsky [mailto:bzbarsky@MIT.EDU] Sent: Monday, October 04, 2010 9:23 AM To: Paul Williams Cc: www-svg Subject: Re: why does <text/> have no firstChild with value "" On 10/4/10 11:13 AM, Paul Williams wrote: > There is a very real, and potentially important semantic difference between the following concepts: > > Empty:<text></text> > Null:<text/> Uh... there is? Last I checked, the latter is just a syntactic shorthand for the former in XML, with no semantic difference (e.g. the DOM, Infoset, etc that are produced are identical). -Boris
