Hey all.

We need to map aria-errormessage on the various platforms, including
ATK/AT-SPI2 and IA2. Given the ongoing desire for cross-platform
homogeneity, I'll toss out what I was thinking for my platform for
consideration by IA2 folks.

Proposal: Connect the message to the element with the error via the
"errormessage" as an object attribute.


1. An error message provides descriptive information about an object.

2. Exposure via a relation eliminates the need to tree dive to find
   the error.

3. Accessible relations can have multiple targets, so this exposure
   does not stomp on a non-error description while at the same time
   eliminating the need for each platform to create a new relation

4. The object attribute is needed to identify which target (if any)
   is an error message.
