<app>

<app> (apparatus entry) contains one entry in a critical apparatus, with an optional lemma and at least one reading. 12.1.1 The Apparatus Entry
Module textcrit — 12 Critical Apparatus
In addition to global attributes In addition to global attributes
type classifies the variation contained in this element according to some convenient typology.
Status Optional
Datatype 

<rng:ref name="data.enumerated"/>
data.enumerated
Values Any convenient descriptive word or phrase, describing the extent of the variation (e.g. word, phrase, punctuation, 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.)
from identifies the beginning of the lemma in the base text, if necessary.
Status Optional
Datatype 

<rng:ref name="data.pointer"/>
data.pointer
Values any valid identifier
Note
This attribute is only used when the double-end point method of apparatus markup is used.
to identifies the endpoint of the lemma in the base text, if necessary.
Status Optional
Datatype 

<rng:ref name="data.pointer"/>
data.pointer
Values any valid identifier
Note
This attribute is only used when the double-end point method of apparatus markup is used, with the encoded apparatus held in a separate file rather than being embedded in-line in the base-text file.
loc (location) indicates the location of the variation, when the location-referenced method of apparatus markup is used.
Status Mandatory when applicable
Datatype 1–∞ occurrences of  

<rng:ref name="data.word"/>
data.word
separated by whitespace
Values Any string containing a canonical reference for the passage to which the variation applies.
Note
This attribute is used only when the location-referenced encoding method is used.
