| 1. A method in a computing device for exchanging context attributes, comprising:
receiving an invocation request to provide an attribute value, the invocation request being generated by a requesting attribute
consumer, the invocation request identifying the attribute whose value is to be provided; and
in response to receiving the invocation request, providing a value for the identified attribute and an associated confidence
level to the requesting attribute consumer, the value having a highest confidence level is provided, and the confidence level
is determined based at least in part on age of the value, wherein the confidence level is adjusted for attenuation over age
of the value at a specified rate based at least in part on the identified attribute.
