As each line in an EpiDoc encoded inscription begins with an lb, attributes on this element can be understood to refer to the content of that line, i.e. all text before the following lb (see also Line Breaks).
In the case of most inscriptions, left-to-right aligned text does not need to be flagged, as it is the default direction. One might need to use rend in the case of boustrophedon text, for instance.
Other values of rend can be created in the case of texts written vertically, in a circle or spiral, or otherwise unusually.‘’Silvio Panciera Josh Sosin
