xf:include and sub-forms
This form illustrates some interactions between the use of
subforms and the xf:include extension supported
by XSLTForms. Its structure is that of the Writers
(Subforms) example at agenceXML.com.
The main form (this document) uses xf:include
to include a message about how many
writers and books there are in the document instance.
The subform loaded
by the Show Books button uses xf:include
to include a different message about how many
books there are for the selected writer.
