Scripting - Check if node attribute is animatable

Hi,

I have a scripting question.

I would like to know how to get the information if a node attribute is animatable or not.

The following attribute seams to be a non-animatable property:
node.getTextAttr(n, 0, “MIN_ANGLE”);

Whereas
node.getTextAttr(n, 0, “SKEW”);
is.

Is there a function allowing to check this attribute property?

Cheers,
