The custom tags you see are Struts 1.0.2 tags
http://jakarta.sun.com/struts/

Expresso has two version of these tags. There are subtle differences

1) Pure 1.0.2 Struts tags

2) Expresso enhanced Struts tags which know about controller elements,
input, outputs, and blocks.

To use either one you specify the TAG LIB DESCRIPTOR (TLD) and
the NAMESPACE in a JSP
e.g

<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="purehtml" %>
<%@ taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="purebean" %>
<%@ taglib uri="/WEB-INF/tld/struts-logic.tld" prefix="purelogic" %>


<%@ taglib uri="/WEB-INF/tld/expresso-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/tld/expresso-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/tld/expresso-logic.tld" prefix="logic" %>
