Custom tags are expressed in "sort of" XML syntax (but without the standard namespace declarations. If you use the XML syntax, you also need to be prepared to put CDATA blocks around all your code inside things like <jsp:expression>. I haven't reviewed what JSP 2.0 came up with as their final answer, but my recollection is that they were focused primarily on improving the usability of the XML syntax, but not on allowing mixing. Need to review the Proposed Final Draft. I stand by my statement that it's a waste of effort for a user (especially a newbie) to take the time to learn both syntaxes. > > Thanks > > > Erik Craig -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
