How to handle alternate section numbers?

[jduff-chs]

In the two Otto editions of Athenagoras I was just working on, as well as in the Aristotle that @josble is formatting the figures and charts for, we are running into sectioning from alternate editions that the editor is printing on the right margin. In both cases, this alternate sectioning is preserved with

<pb ed="alt" n="1A">

Is this the right way for handling this? I notice that it is read in Nemo in the same way as other page breaks, and in reality it isn't a page break, but an alternate sectioning. Should we be preserving these alternate structures at all? If so, should we consider using milestones or something similar to distinguish them from the page breaks or segments of the actual edition we are working with?

See an example below:

<div type="textpart" subtype="chapter" n="3"><p>Τρία ἐπιφημίζουσιν ἡμῖν ἐγκλήματα, ἀθεότητα, Θυέστεια <pb ed="alt" n="4C"/>
δεῖπνα, Οἰδιποδείους μίξεις. Ἀλλὰ εἰ μὲν ἀληθῆ ταῦτα,
μηδενὸς γένους φείσησθε, ἐπεξέλθετε δὲ τοῖς ἀδικήμασι· σὺν
γυναιξὶ καὶ παισὶ προῤῥίζους ἡμᾶς ἀποκτείνατε, εἴ γέ τις Χριστιανῶν
ζῇ δίκην θηρίων. Καίτοι γε καὶ τὰ θηρία τῶν ὁμογενῶν
<pb n="v.2.p.16"/>

The corresponding portion of the original document and Nemo-formatted version can be found attached.

I think, indeed we don't want those "alternate pagebreaks" to show up as actual pagebreaks in our XML. It looks more like an information to me, which belongs in some kind of milestone. What do you think, @PonteIneptique, change the "pb" into "milestone"? so instead of <pb ed="alt" n="4C"/> make it <milestone unit="altchapter" n="4C"/> ?

[PonteIneptique]

Agreed (probably altnumbering even ;) and 4.C)

[jduff-chs]

Fantastic, thanks, we'll get to work implementing that!

[annettegessner]

Ok, so in the future we solve this with: <milestone unit="altnumbering" n="1.A"/>
