    | hand | In the case of damage (deliberate defacement, inking out, etc.) assignable to a distinct
        hand, signifies the hand responsible for the damage. | Status | Optional |  | Datatype |  |  | Values | must be one of the hand identifiers declared in the document header (see section 11.4.1 Document Hands). | 
 |  | agent | categorizes the cause of the damage, if it can be identified. | Status | Optional |  | Datatype |  |  | Sample values include: | rubbingdamage results from rubbing of the leaf edgesmildewdamage results from mildew on the leaf surfacesmokedamage results from smoke
 | 
 |  | degree | Signifies the degree of damage according to a convenient scale. The damage tag
        with the degree attribute should only be used where the text may be read with
        some confidence; text supplied from other sources should be tagged as supplied. | Status | Optional |  | Datatype |  |  | Values | a coded representation of the degree of damage, either as
 a number between 0 (undamaged) and 1 (very extensively damaged), or
      as one of the codes high, medium, low. |  | Note | The damage  tag with the degree  attribute should only be used where
          the text may be read with confidence despite the damage. It is appropriate where it is
          desired to record the fact of damage, though this has not affected the readability of the
          text (as may be the case with weathered inscriptional materials). Where the damage has
          rendered the text more or less illegible either the unclear  tag (for partial
          illegibility) or the gap  tag (for complete illegibility, with no text supplied)
          should be used, with the information concerning the damage given in the attribute values
          of these tags. See section 11.5.2 Use of the gap, del, damage, unclear, and supplied Elements in Combination  for discussion of the use of these tags
          in particular circumstances. | 
 |  | group | assigns an arbitrary number to each stretch of damage regarded as forming part of the
        same physical phenomenon. | Status | Mandatory when applicable |  | Datatype |  |
