all identifiers indexed in a compound definition line?
Yes, assuming no parse errors are encountered in any of the identifier strings among all component definition lines, all of the identifiers are indexed by default. If only a subset of identifier types needs to be indexed for later use in retrieval, indexing can be restricted to a subset of types with one or more ‑T specifications on the xdformat command line. Similarly, indexed retrieval can be restricted to a subset of identifier types by specifying one or more ‑T specifications on the xdget command line. Of course, ‑T restrictions are only effective if the corresponding identifiers actually appear in the database. Any ‑T index restrictions imposed during database creation on the xdformat command line automatically (and unconditionally) remain in effect during appends of additional data to the same database; the restrictions need not be replicated on the xdget command line unless even tighter restrictions are desired during retrieval. Tighter restrictions upon retrieval can be obtaine
