Conflicts: xfa Template keeps main's embedded/embedded_paths and this
PR's cache (parse() sets all three); engine xfa.rs tests keep both
sides' tests; xfa README combines main's sheet numbers with this PR's
property objects; parity form.xfa-dynamic keeps this PR's notes plus
main's floating-field sentences and both sides' evidence.
