[License-discuss] a GPLv3 compatible attribution for MIT/BSD?

[Clark C. Evans]

Good Morning!

Our company is releasing a medical informatics platform, RexDB,
under the GPLv3 license later this year (after the code has a
developer documentation).  We will be using 7b clause
of the GPLv3 license for a reasonable author attribution.

Even so, parts of our system will be released under a more
permissive license, and I'm wondering if there is a simple,
MIT-style clause that would be compatible with the GPLv3?

Here's my crayon attempt... 

  To the extent that an application using this software
  displays legal notices, copyrights, or attributions it 
  must acknowledge the Example Project (http://example.org)
  in a similar manner.

Would this sort of clause be compatible with GPLv3 and would
it meet the OSI criteria?  Would anyone have specific wording
suggestions?  I'm asking here because I'd rather re-use
something similar, if not, then I'd prefer to be adding a
clause that has "consensus" here.

Thank you kindly.
