I asked our standards expert, and there is nothing being proposed for
extended attributes, e.g., no specifications for -@ options for
utilities. There is a draft of a subset of functionality for
*at() interfaces (operations against
a path relative to a fd) proposed for *possible* inclusion in the next
revision of SUSv3, but again, not dealing with extended attributes.
