An XProc script is edited as an XML document that is validated against a RELAX NG schema. If the script has an associated transformation scenario, then the XProc engine from the scenario is invoked as validating engine. The default engine for XProc scenarios is the Calabash engine which comes bundled with Oxygen XML Editor version 17.0.
The content completion inside the element input/inline from the XProc namespace http://www.w3.org/ns/xproc offers elements from the following schemas depending both on the port attribute and the parent of the input element. When invoking the content completion inside the XProc element inline, the Content Completion Assistant's proposals list is populated as follows:
- If the value of the port attribute is stylesheet and the xslt element is the parent of the input elements, the Content Completion Assistant offers XSLT elements.
- If the value of the port attribute is schema and the validate-with-relax-ng element is the parent of the input element, the Content Completion Assistant offers RELAX NG schema elements.
- If the value of the port attribute is schema and the validate-with-xml-schema element is the parent of the input element, the Content Completion Assistant offers XML Schema schema elements.
- If the value of the port attribute is schema and the validate-with-schematron element is the parent of the input element , the Content Completion Assistant offers either ISO Schematron elements or Schematron 1.5 schema elements.
- If the above cases do not apply, then the Content Completion Assistant offers elements from all the schemas from the above cases.
The XProc editor assists you in writing XPath expressions by offering a Content Completion Assistant and dedicated coloring schemes. To customize the coloring schemes, open the Preferences dialog box and go to .
