Hi Generous Members of TEI-L,

How would one go about recording differences in line indentation between two different appearances of a poem?

For instance, consider two appearances of a poem. One looks like this:

The sun sought thy dim bed and brought forth light,
The sciences were sucklings at thy breast;

The other is identical except that the second line is indented. What's the best way to capture this?

For other types of textual variation, an <app> with <lem> and <rdg>s works seems pretty straightforward to me. I have, however, been encoding line indentation as @rends on the individual lines; is that my problem? Is there a sane way to record these sorts of variation in line indentation? (I'm not opposed to changing the way I'm encoding line indentation if that is the problem.)

Thanks very much,
