<macro:custom-macro-name>

The use of a custom EMML statement defined in a macro of that name. To use macros in a mashup script, you must declare the macro reference namespace and use the namespace prefix with your custom macro name.

Pass input parameters to the custom macro as attributes in this statement. Use the outputvariable attribute to identify the variable that should receive the results of the macro, if any.
