WorldServer supports two general CSV formats: Simple and Advanced.
In Simple CSV format, which might be used to contain a glossary, each row is a term entry. Columns might contain locale instances (terms) for the term entry. Other columns might contain term entry attribute values.
In Advanced format, each row contains a locale instance (that is, one term) for an entry, with columns for the language, the term, and each attribute. An entry therefore is comprised of multiple rows, one for each term in the entry.
