EDIT

No this is a misunderstanding. The requirement is:

Do not show character and value for characters of property present/absent if and only if

1. there state is present and only present (if both states exist it must be shown) AND
2. if values for subcharacters exist. (in the above description you say that the subcharacter should be subpressed, this is not case)

It also can't be handled during aggregation, because the information might be needed on higher levels of aggregation.
Therefore this is only a display/publication issue and needs to be handled in output (either in webservice or in dataportal).

I adapted the description to avoid misunderstandings

In your comment you seem to suggest to show the following situation:

Inflorescence = absent
|
+- leaf color = red 
+- leaf count = 5

Why would you want to show a property of a state which is not present at all?

This doesn't make sense to me.

This case usually is dirty or incomplete data. Dirty data should be shown on the portal to make it findable (correctable). Of course also the aggr. algorithm should report such data as warning.

By the way: it could even be only incomplete data. If someone entered only presence = absent. For those species/specimen where presence = present it was not reported and therefore subcharacters were entered correctly. On higher aggregation level this can happen as the 2 informations link back to different child taxa descriptions. What is missing here is a count for missing data. This might be discussed. But this is another ticket. #8762
