I wonder if anyone could comment. I have a requirement to add a query  
param to the shire param that's sent from an SP to an IdP but the  
shire doubles as the providerId and the dynamic content of the query  
param breaks the metadata matching.

shire=https://sp.mysite.com?entityID=DYNAMIC_CHANGES_ALL_THE_TIME

Is there any way in the IdP to separate the providerId from where the  
response to the SP should go (shire)? Or is there a way to regex the  
metadata matching to ignore the query param?

My SP needs to preserve some state at it's end based on the response  
from the IdP. The only way it can do that is adding a query param to  
the shire IdP param.

Ideally, it would be good if the IdP could "bounce" something back to  
the SP that made sense to the SP.
