+\section{Tags supported by wxHTML}\label{htmltagssupported}
+
+wxHTML is not full implementation of HTML standard. Instead, it supports most common tags so that it 
+is possible to display {\it simple} HTML documents with it. (For example it works fine with pages created
+in Netscape Composer or generated by tex2rtf).
+
+Following tables list all tags known to wxHTML, together with supported parameters.
+A tag has general form of {\tt <tagname param\_1 param\_2 ... param\_n>} where param\_i is
+either {\tt paramname="paramvalue"} or {\tt paramname=paramvalue} - these two are equivalent. Unless stated 
+otherwise, wxHTML is case-insensitive.
+
+
+\wxheading{Table of common parameter values}
+
+We will use these substitutions in tags descriptions:
