Questions about continuant fiat boundaries

[johnbeve]

^{Originally posted by gregfowlerphd September 5, 2024} This isn't really a bug, just a series of questions (though I suppose it's possible they might lead to a bug being uncovered).

The elucidation of ‘continuant fiat boundary’ reads:

A continuant fiat boundary b is an immaterial entity that is of zero, one or two dimensions & such that there is no time t when b has a spatial region as continuant part & whose location is determined in relation to some material entity

The final clause here suggests, without outright stating, that every CFB is a boundary of some material entity. Is that suggestion correct?

Also, while the elucidation indicates that every CFB’s location is determined in relation to some material entity, can a CFB’s location also be determined in relation to something that isn’t a material entity? And can a CFB be a boundary of something that isn’t a material entity?
