Further on,

if I translate the grammar above using trang into XML Syntax, the referenced file is translated
into 'grammar' element, and the grammar is still invalid. If I remove the wrapping grammar element,
then the grammar is valid.

If I then translate the valid XML RNG schema into either XML or compact syntax using trang,
I get invalid grammar.

I'm lost.  The question is not whether trang is perfect or not. The question is whether there is
an implicit grammar in a file consisting of  a single pattern. and if there is, why nXML and jing
both complain when I try to include testi.rnc (include "testi.rnc"; either syntax error or 'not
a grammar').
