In case people aren't aware, it's a restriction in the JSP spec ... and,
the ultimate reason is that it's invalid XML syntax as well.

The standard approach to this requirment in JSP is to use runtime
expressions. Where you might want to write
<tag attribute="<bean:write name="foo" property="bar.baz"/>" />
you can write this instead:
<jsp:useBean id="foo" class="..." scope="..."/>
<tag attribute="<%= foo.getBar().getBaz() %>" />
