<interp> (interpretazione) riassume una specifica annotazione interpretativa che può essere associata ad una porzione di testo [17.3 Spans and Interpretations]
Generally, each interp element carries an xml:id attribute. This permits the encoder to explicitly associate the interpretation represented by the content of an interp with any textual element through its ana attribute.
Alternatively (or, in addition) an interp may carry an inst attribute which points to one or more textual elements to which the analysis represented by the content of the interp applies.
