photo = element photo
{   attribute cat-no { text },      1
    attribute url { xsd:anyURI }?,  2

The cat-no attribute is required, and specifies the catalog number of the image.

2

If there is a rendering of this photo available on the web, use the url to specify its Universal Resource Identifier. Optional.

This attribute is used in the process of linking photos. A program generates photo elements and annotates them with the form code from the ab6 field so the prefab XML elements can be quickly dropped into the notes file.

You can add text content to a photo element for remarks on the photo.
