dtddiff of XSDL November and September drafts
Date: Tue, 9 Nov 1999 12:10:55 -0500 From: "DuCharme, Robert" <DuCharmR@moodys.com> To: xml-dev@ic.ac.uk Subject: dtddiff of XSDL November and September drafts
Below is the output of Earl Hood's dtddiff utility (see http://www.oac.uci.edu/indiv/ehood/perlSGML.html for his collection of perlSGML utilities) when comparing the DTD from the November 5th draft of the W3C XML Schema proposal with the one from the September 24th version. The two-column arrangement is easier to read in monospaced type. Note that content model differences are highlighted by the use of all caps for the changed parts.
