How are handled generic values' ID for elements defined in value lists?

Hi,

I am not able to figure out any rigorous systematism in the definition of the ID of elements in the value lists definitions in qwat.

For example; here is the list of the pipe material values in qwat_vl.pipe_material where code_sire=6:

From this table, I can decide to use the pipe with ID=5700 as "a generic PVC pipe" (i.e. having the strict minimal set of data, with no diameter(s) specified) to quickly import SIRE data into the qwat model.

But for some other pipes, there is no such equivalent "generic pipe", e.g. PE 100 pipes with a code_sire=7:

An idea could be to set the qwat ID to `xyyy` with `x`=`code_sire` and `yyy`=`000` for a "generic pipe", and then, for all specific pipes, using `yyy`=`001` to `999`.

For example, when code_sire=6, the pipe with ID=6000 would be the generic PVC pipe with the minimal set of data (i.e. only the material definition) and pipes 6001 to 6999 would be well defined pipes (with specific diameters and so on).
