I find it works with well-formed XML in p:inline.

<p:input port="source">
  <p:inline><document><!-- dummy document--></document></p:inline>

One way is to use p:data

Calabash 1.0.18 had a known problem reading plain text input with
p:data, but that has been fixed in 1.0.19-b1
(https://github.com/ndw/xmlcalabash1/issues/154). However, just now I
encountered a different problem trying to use p:data/p:with-option.
