  We examine the basic assumptions underlying a scenario due to Kibble that is
widely used to estimate the production of topological defects. We argue that
one of the crucial assumptions, namely the geodesic rule, although completely
valid for global defects, becomes ill defined for the case of gauged defects.
We address the issues involved in formulating a suitable geodesic rule for this
case and argue that the dynamics plays an important role in the production of
gauge defects.
