... I don`t understand. Maybe I haven't described the Problem not well.
The docs with doc.Standard have:
{
Type: KK,
Sign:1111,
Standard:CE3,
.
.
.
}
This means that I have only one kind of Standard in a doc. I think its
right that it is not possible to conserve information from doc to doc on the
map side. Therefore I have to emit the Standard value ...
