Abstract
We give effective necessary and sufficient conditions for a
quadratically defined 2-relator pro-p-group to
be mild and apply these results to give examples of 2-extensions
with restricted ramification over an imaginary quadratic base
field for which the associated Galois group is a mild
2-relator pro-2-group.
