Remarks

The alternatives provided in lem and/or rdg sub-elements may be thought of as exclusive or as parallel. The type attribute may contain any convenient descriptive word, describing the extent of the variation (e.g., note, phrase, measure, etc.), its text-critical significance (e.g., significant, accidental, unclear), or the nature of the variation or the principles required to understand it (e.g., lectio difficilior, usus auctoris, etc.).

The model of this element is based on the app element of the Text Encoding Initiative (TEI).
