+	* xml.el (top level comment): Updated to reflect the fact that
+	white spaces are relevant in the XML file
+	(xml-parse-file): Do not kill an existing Emacs buffer if the file
+	to parse was already edited. This allows for on-the-fly analysis
+	of XML files
+	(xml-parse-tag): Check that the casing is the same in the start
+	tag and end tag, since XML is case-sensitive.  Allows for spaces
+	in the end tag, after the name of the tag.
+	(xml-parse-attlist): Allow for the character '-' in the name of
+	attributes, as in the standard http-equiv attribute Do not save
+	the properties in the XML tree, since they are not relevant
