An optional, non-repeating, group of data elements which together describe features of the content of an edition of a religious text, and intended to meet the special needs of religious publishers and booksellers. The <ReligiousText> composite may carry either a <Bible> composite or a <ReligiousTextIdentifier> element accompanied by multiple repeats of the <ReligiousTextFeature> composite. This approach is adopted to enable other devotional texts to be included if need arises without requiring a new ONIX release.
