|</p:declare-step>Description
The p:message step is a
standard XProc 3.0 step.
If the test option
evaluates to true, the select option is evaluated and
the string value of that expression is displayed as a message. If the test
option is false, the message is not displayed.
In either case, this step behaves like the p:identity step.
