"Preserves <something>", for example "Preserves data", reads like "it preserves data". Probably less so in the middle of a sentence, due to the uppercasing, but in the TOC it reads like bullet points enumerating what is preserved.

Thank you! I wonder if something a bit contrived such as small-caps could help. I'll experiment.

Putting Preserves in italics would be an alternative.

The name nevertheless feels awkward to me, also in spoken conversation. A made-up word like maybe “Pres” or “Edal” (from “expressive data language”) would work better IMO.
