For occurrances of <param-ref name="[struct-ref-name]">, the XSLT will find and apply the corresponding <struct-ref> with the name [struct-ref-name], and add it as a parameter. The javascript filter mechanism must be adapted because this introduces a new level of nested collapsible elements.
-
<param-ref>is only processed inside of<program>and<struct-ref>tags, because it is an alternative to the<param>tag. -
Using the attribute
as-param="[custom name]"we can specify the name of the parameter independently from the<struct-ref>s name (which is only used to identify the corresponding<struct-ref>definition).
