why is the scale manip offering "local" mode only?

Hi there,

just having transfered to XSI for modeling a while ago
I still lack the understanding for some transformation
options specific to XSI 5.11:

For what reason does a polygon object sometimes
refuse to be scaled in any other mode but "local"?

I can of course freeze construction history and transforms,
click "Set neutral pose" and then am allowed to use
"world" or "reference" mode but again, why is that?

That´s just as puzzling as the way the object/transform pivots
work. In Maya, I can set the pivot to a specific location,
freeze transforms and start keying SRT´s with zeroed out
transforms while still having the pivot offset.

Obviously, XSI is far more flexible, especially with "COG",
"add" and "ChildCompensation" options available on the fly
but this also means my hierarchies are stuffed with nulls everywhere.

While on the other hand, splitting XYZ rotations up into a chain
of three nulls (under the hood, one for each axis) to avoid flipping
while rotating isn´t implemented as a "mode" althought it would
likely be a nice feature/functionality - especially if not required
to be manually created for each object.

Cheers

tim
