I think a border elements should be designed to “set solid”. i.e., a 12 pt. border with 12 pt. leading should align correctly. It’s much easier than setting 12 pt. on 14.4, or 11 pt. on 13.2.

Word and the like can be set to exact line spacing, and borders are more likely to be used in a DTP app, where people are less likely to use default percentage based leading.

You _will_ provide all the rotations necessary to make a simple box, won’t you? Some fonts require the user to rotate elements, while the font’s EULA forbids the user from modifications...argh! And, please, don’t rely on kerning for horizontal positioning!

Other ornaments, leaves and the like, just have to “look good” when set in a line with text. Of course, what “looks good” beside a uc A will look too high beside a lc a, or a smallcap A. I suppose one could make use of “case forms” in OpenType to help with that.

Ornaments to be used with lines of text should relate in the vertical alignemnts. Village ornaments contains two different solutions to borders that’d be hard to explain but easy to see...
