Different types of non-standard transmission

[Jean-Baptiste-Camps]

For now, we have only: standard filiation and lateral transmission (i.e., contamination).

But, in some cases, a node is shown to have more than one "standard" ancestor (without dashes on the stemma), e.g., both used on the same level, or one used for part 1 and the other for part 2. Could it be possible/desirable to distinguish:

• multiple ancestry on the same level
• lateral transmission (= contamination).

e.g., plan.a and plan.b on #62 , who has multiple ancestry AND also contamination.

So, for multiple ancestry,

planA->marcianus;
planB->marcianus;

and then contamination,

beta->marcianus[style="dashed"];

[Jean-Baptiste-Camps]

NB: In the case where a manuscript has two successive models, it would make sense for him to have to sigla, and be represented at two places in the tradition, but it has not always be done like this.

[Jean-Baptiste-Camps]

In other cases, in the stemma, it is shown as a node with only incoming contamination and no direct "standard" parent, like in #147 . This is as much problematic !
See the case of w_a.
