This is an extension step; to use it, your pipeline must include its declaration.
For example, by including the extension library with an import at the top of your
pipeline:
<p:import href="https://xmlcalabash.com/ext/library/polyglot.xpl"/>Declaration
1 |<p:declare-step xmlns:p="http://www.w3.org/ns/xproc">
| <p:input port="source" primary="true" sequence="true">
| <p:empty/>
| </p:input>
5 | <p:input port="program" content-types="text"/>
| <p:output port="result"/>
| <p:option name="args" as="xs:string*"/>
| <p:option name="result-content-type" as="xs:string?"/>
| <p:option name="parameters" as="map(xs:QName,item()?)?"/>
