The Extent Specification within the File Description (//fileDesc/extent)

An <extent> element within the File Description is used to specify the extent of the DTA full text. The extent is given in several <measure> elements in different units (facsimile files, tokens, types, characters).

<extent>
      <measure type="images">[extent: number of facsimile files]</measure>
      <measure type="tokens">[extent: number of tokens]</measure>
      <measure type="types">[extent: number of types]</measure>
      <measure type="characters">[extent: number of characters]</measure>
</extent>
