int usd_isarray(<stage>stage, string primpath, string name)

When running in the context of a node (such as a wrangle LOP), this argument can be an integer representing the input number (starting at 0) to read the stage from. The integer is equivalent to the string form referencing a particular input, e.g., "opinput:0".
primpath
The path to the primitive.
name
Attribute name.
Returns
1
if the attribute exists and is an array, or 0
otherwise.
