+
+	Corrected a bug in the compilation of metacalls whose meta-arguments are 
+	variables.
+
+	Removed references to file sax.jar from the scripts used to convert XML 
+	documenting files into (X)HTML. Updated scripts html.sh, htmlnt.cmd, and 
+	htmldos.bat to use XT 20020426a or later version.
+
+	Improved syntax coloring accuracy of built-in predicates and methods for 
+	the SubEthaEdit text editor.

+The method <code>parameter/2</code> is only compiled in-ilne when used inside objects; its use inside categories implies a call to the built-in Prolog predicate <code>arg/3</code>. Nevertheless, note that calls to <code>parameter/2</code> from inside categories are inherently problematic: a category may be implemented by several objects, both parametric (with different number of parameters) and non-parametric. Care must be taken to ensure that a parametric object importing such a category match the interpretation of its parameters used in the category.
