A fixed [lexicon] is a lexicon that has values provided by High Line that are part of the system [seed data].  The values that a fixed lexicon imparts are fixed inasmuch as there is usually programming that is looking for specific values.

Rules regarding fixed lexicons:
* If you delete any fixed lexicon values, they will be re-added when this [seed data] is next reloaded
* Changing the descriptive meaning (display value) of this lexicons is discouraged because:
** The original descriptive meaning will be restored when you reload this seed data next
** There may be specific programing that will be confounded by a user's expectation (given the change in meaning)
* Adding new values to this lexicon is discouraged because:
** Any values added will be removed when the seed data is next reloaded
** There will be no programming to support your additions.

If you have a need to add to a fixed lexicon, it is recommended you contact [High Line Support|mailto:support@highlinecorp.com]
