I'm sorry if bits were unclear - do feel free to ask questions about

Might there be an approach to the application where you don't use XSLT
to produce JSP?  For example, XSLT can take parameters (and it's even
fairly simple to use them if you use a server-side application
environment such as Cocoon), so it might be that you can pass
parameters into the XSLT, and therefore just use:

   <input type="hidden" name="ProductID" value="{$productid}" />

Ah... OK, I see why - the spec says "The html output method should not
escape < characters occurring in attribute values."  The processor is
using the HTML output method, so isn't escaping the <s.
