Dear all,
the tag infraAttrGroups is a container for pre-defined infrastructure
attributes. One would use it to mark e.g. all tracks that have a common
property, e.g. traction 25kV or similar gauge.
In a way, this is similar to unix groups. A user belongs to group "lp,
printer, scanner group".
I think this is the idea behind infraAttrGroups. At present, <track> has
an attribute infraAttrGroupRef. In other words, it is not possible to
create a relation between one <track> and more than one <infraAttrGroup>.
If a track points to more than one infraAttrGroups, we could emulate the
unix-style group usage. This implies that <track> needs a 0..n children
<infraAttrGroupRef>
How about it ?!
ps. this is my first and probably not my last contribution !
