STR:
* Have someone else use "Windows Remote Assistance" to send an invitation via email to a TB user.
* The TB user receives the email and double-clicks on the attachment.

Actual:
* TB offers to open via an "XML Editor" and offers no other reasonable suggestions.

Expected:
* TB offers to open via the "remote assistance" application.

Work-around is to save the attachment to the filesystem then double-click on it there.

The problem is that Remote Assistance sends an attachment with a content-type of XML, but with an extension which is associated with the Remote Assistance application.  TB appears to prefer the content-type over the file-extension association.

For example, the message source of one such message includes:
"""
... <some of the text/plain portion removed .../>

To accept this invitation, double-click the file attached to this message.

...
--------------000506090109050504060100
Content-Type: text/xml;
 name="Invitation.msrcincident"
Content-Disposition: attachment;
 filename="Invitation.msrcincident"

<?xml version=3D"1.0"?>
...
"""

I understand the decision to prefer content-type over the associated file extension might be a policy decision, but this would be frustrating for people; if there is a whitelist or similar this might be worth considering.
