Remarks

A patch must always contain a folium or bifolium element. The @x and @y attributes are used to position the patch on its parent surface by indicating the upper left corner of the patch. The size of the patch is encoded using the @height and @width attributes on the child folium (or bifolium).

Constraints

The allowed positions of a patch depend on its parent element.
A patch element must contain either a folium or a bifolium element.
