That would be in src/mac/lib/mac_util.c

Have a look in the design documents, while you're looking around.

A Trix MAC label has two parts, a sensitivity, and an integrity.
Each of these has a type part, a heirarchical part, and a set part.
The Text form will be one of:

	<alias> || <sensitivity>/<integrity>

sensitivity::
	<msentype> ||
	<level>[,<category>]... ||
	<msentype>,<level>[,<category>]...

integrity::
	<minttype> ||
	<grade>[,<division>]... ||
	<minttype>,<grade>[,<division>]...

Aliases are defined (in Trix 6.5.x) in /etc/mac. An example:

userlow:alias:msentcsec,unclassified/mintbiba,lowestgrade
