Note

A specification group is referenced by means of its xml:id attribute. The declarations it contains may be included in a schemaSpec or moduleSpec element only by reference (using a specGrpRef element): it may not be nested within a moduleSpec element.

Different ODD processors may generate representations of the specifications contained by a specGrp in different concrete syntaxes.
Example
<specGrp xml:id="xDAILC">
 <elementSpec ident="s">
<!-- ... -->
 </elementSpec>
 <elementSpec ident="cl">
<!-- ... -->
 </elementSpec>
 <elementSpec ident="w">
<!-- ... -->
 </elementSpec>
 <elementSpec ident="m">
<!-- ... -->
 </elementSpec>
 <elementSpec ident="c">
<!-- ... -->
 </elementSpec>
</specGrp>

This specification group with identifier xDAILC contains specifications for the elements s,cl,w, etc.
