The src atttribute for state and parallel was removed from the specification 
several years ago, May 2010, with the suggestion to use the xinclude standard

Deprecate seems the reasonable thing to do as the xinclude solution is said to 
provide a superior version of the same functionality. But that should be 
validated and properly tested first before dropping the current implementation. 
But that shouldn't happen anyway until the next major release for SCXML, after 
the 2.0 release.

Side note: the <data> and <script> elements also have optional usage of an 
external src, not just <invoke>.
