Similar observations are true of an average case of literary encoding, to which grammatical information gets added for the purpose of enhancing searches or for basic measurements -it can be added as a separate document, i.e.
apart from @lemma and @lemmaRef, up till now TEI encoders could only resort to using the generic attribute @ana for inline linguistic annotation, or to the quite complex system of feature structures for robust linguistic annotation, the latter requiring relatively complex processing even for the most basic types of linguistic features.
