changed mode from "delete" to "replace" on classSpecs to be removed.  This is a workaround for an apparent bug in Roma.
1. add @translit to the att.lang class
2. make most elements that allow text (that weren't already members) members of att.lang. The elements altId, f, harm, hex, key, and line are unchanged.
