The includes keyword must be followed by comma separated list of trait
references.  So

  t: trait

    includes
      String(byte, data),
      Natural(nat)
      attr tuple of d: data, n: nat

will work.

LSL syntax and semantics are covered in DEC SRC technical report #58 which you
can obtain via WWW at

	http://www.research.digital.com/SRC/publications/src-rr.html

or by ftp

	ftp site:	gatekeeper.pa.dec.com
	file:		/pub/DEC/SRC/research-reports/SRC-058.ps.Z

Best of luck,

Patrice
