Integration Architect? Who's that?

I've searched the web a good deal to find out an Integration Architect's role and responsibilities, and found quite a few definitions. But most of them seem to be specific to a requirement, so I thought I should create one that is more generic. According to me, an Integration Architect would be the one who defines the architecture for integrating applications (using a tool or a framework) and creates a methodology for implementing "Integrations" or "Interfaces" between applications using the defined architecture.

He/she would typically go through the standard development lifecycle from inception to delivery. The involvement from the architect's perspective would be heavy during inception, light in the middle and moderate towards the end. Tasks the architect would perform in the large middle period would be guiding the implementation team and towards the end would largely be validating the solution against the requirements.
