Write an NCX value in XML encoding while checking nodes for suppression of output with the supplied test fn.

!!! NOTE !!!

This function generates the contents of the val_value_t but not the top node itself. This function is called recursively and this is the intended behavior.

To generate XML for an entire val_value_t, including the top-level node, use the xml_wr_full_val fn.

If the acm_cache and acm_cbfn fields are set in the msg header then access control will be checked If FALSE, then nothing will be written to the output session
