Maybe we don't need the "type" attribute if we offer the more detailed
attributes below.

A stop post may have additional signs which indicate whom stop position
they are requesting. The train length is a widely used example for
that. A short train has to stop at another position than a long train
(for several reasons). The other mentioned constraining characteristics
are not so widely known, but appear in some cases.
A freight train with only few axles has to stop at another position
then a train with a larger number of axles. I don't know why it is
sometimes defined with axle numbers and sometimes with wagon numbers,
maybe for some historical reasons (as always).
de: Eine Halttafel hat in einigen Fällen ein Zusatzschild, welches
angibt, für welche Züge diese Halteposition gilt. Die Angabe einer
Zuglänge ist eine weit verbreitete Zusatzinformation in diesem
Zusammenhang. Die anderen oben aufgeführten Einschränkungen treten
eher selten auf, sind jedoch nicht gänzlich unbekannt.
"100m" (Züge bis 100m Länge),
"40x" (Züge bis zu 40 Achsen)
"Langzug" (S-Bahn-Langzüge)
read you soon...
