XML Calabash Namespaces
XML Calabash uses several extension namespaces:
http://xmlcalabash.com/ns/extensions
http://xmlcalabash.com/ns/extensions/fileutils
http://xmlcalabash.com/ns/extensions/marklogic
http://xmlcalabash.com/ns/extensions/xmlunit
The easiest way to use the steps that are defined in these namespaces is by importing the extension library:
<p:import href="http://xmlcalabash.com/extension/steps/library-1.0.xpl"/>
Note that importing this library incurs no network traffic. XML Calabash recognizes the URI and accesses the set of declarations internally.
