att.textCritical

att.textCritical defines a set of attributes common to all elements representing variant readings in text critical work. [12.1 The Apparatus Entry, Readings, and Witnesses]
Moduletextcrit — 12 Critical Apparatus
Memberslem rdg rdgGrp
Attributesatt.responsibility (@cert, @resp)
wit(witness or witnesses) contains a list of one or more pointers indicating the witnesses which attest to a given reading.
Status Optional
Datatype 1–∞ occurrences of 

<rng:ref name="data.pointer"/>
data.pointer
separated by whitespace
Values A space-delimited series of sigla; each sigil should correspond to a witness or witness group and occur as the value of the xml:id attribute on a witness element elsewhere in the document.
Note
If the apparatus contains readings only for a single witness, this attribute may be consistently omitted.
This attribute may occur both within an apparatus gathering variant readings in the transcription of an individual witness and within an apparatus gathering readings from different witnesses.
Additional descriptions or alternative versions of the sigla referenced may be supplied as the content of a child wit element.
typeclassifies the reading according to some useful typology.
Status Optional
Datatype 

<rng:ref name="data.enumerated"/>
data.enumerated
Sample values include:
substantive
the reading offers a substantive variant.
orthographic
the reading differs only orthographically, not in substance, from other readings.
causeclassifies the cause for the variant reading, according to any appropriate typology of possible origins.
Status Optional
Datatype 

<rng:ref name="data.enumerated"/>
data.enumerated
Sample values include:
homeoteleuton
homeoarchy
paleographicConfusion
haplography
dittography
falseEmendation
varSeq(variant sequence) provides a number indicating the position of this reading in a sequence, when there is reason to presume a sequence to the variants on any one lemma.
Status Optional
Datatype 

<rng:ref name="data.count"/>
data.count
Values a positive integer
Note
Different variant sequences could be coded with distinct number trails: 1-2-3 for one sequence, 5-6-7 for another. More complex variant sequences, with (for example) multiple branchings from single readings, may be expressed through the join element.
handsignifies the hand responsible for a particular reading in the witness.
Status Optional
Datatype 

<rng:ref name="data.pointer"/>
data.pointer
Values must be one of the hand identifiers declared in the document header (see section 11.3.2.1 Document Hands).
Note
This attribute is only available within an apparatus gathering variant readings in the transcription of an individual witness. It may not occur in an apparatus gathering readings from different witnesses.
Note
This element class defines attributes inherited by rdg, lem, and rdgGrp.
