RELAX NG: Are Grammar Elements Always Required to Contain a Start Child

["Rudick, Tom" <tmrudick@mitre.org>]

Hello All,

 

I am somewhat new to RELAX NG and just starting to get my feet wet with more complex topics.  I am trying to create a "modular" schema by making use of the <include> element.  I have followed the schemas used in the RELAX NG Tutorial (http://www.oasis-open.org/committees/relax-ng/tutorial.html) in section 9.3 to merge grammars using the <include> element.

 

However, both my current editor (OxygenXML) and jing, tell me that the document to be included is 'missing "start" element' and that it is invalid.  I have noticed that in section 4.18 of the RELAX NG Specification (http://www.oasis-open.org/committees/relax-ng/spec-20011203.html#IDASNZR) is stated, "A grammar must have a start child element." 

 

Does this mean that I cannot correctly create a schema that does not have a start element, even though it is to be included in another schema?  Or am I interpreting section 4.18 incorrectly?

 

Thanks in advance,
