<surface>

<surface> defines a written surface as a two-dimensional coordinate space, optionally grouping one or more graphic representations of that space, zones of interest within that space, and transcriptions of the writing within them.

Note
The surface element represents any two-dimensional space on some physical surface forming part of the source material, such as a piece of paper, a face of a monument, a billboard, a scroll, a leaf etc.
The coordinate space defined by this element may be thought of as a grid lrx - ulx units wide and uly - lry units high.
The surface element may contain graphic representations or transcriptions of written zones, or both. The coordinate values used by every zone element contained by this element are to be understood with reference to the same grid.
Where it is useful or meaningful to do so, any grouping of multiple surface elements may be indicated using the surfaceGrp elements.
