The facs attribute is available globally when the transcr module is included in a schema. It may be used to point directly to an image file, as in the following example:

<msItem>
 <locus
   facs="images/08v.jpg images/09r.jpg images/09v.jpg images/10r.jpg images/10v.jpg">fols. 8v-10v</locus>
 <title>Birds Praise of Love</title>
 <bibl>
  <title>IMEV</title>
  <biblScope>1506</biblScope>
 </bibl>
</msItem>
註
The target attribute should only be used to point to elements that contain or indicate a transcription of the locus being described, as in the first example above. To associate a locus element with a page image or other comparable representation, the global facs attribute should be used instead, as shown in the second example. Use of the target attribute to indicate an image is strongly deprecated. The facs attribute may be used to indicate one or more image files, as above, or alternatively it may point to one or more appropriate XML elements, such as the surface, zone element, graphic, or binaryObject elements.
