Support Multiple Languages
Add language code and script code attributes to all non-empty elements <unittitle lang=“eng”

Make sure appropriate elements can repeat to support multi-language description

Reduced Mixed Content
Reduce mixed content by more carefully considering what elements are appropriate within a given element
Balance that impulse against desire for reasonably simple schema design
