When an implementation of the LRA specification invokes any of the
participant callbacks (namely {Compensate}, {Complete},
{Status}, {Forget}, and {AfterLRA}) in the context
of a nested LRA it must ensure that the parent LRA is made available
via an HTTP header field with the following name. The value contains
the parent LRA context associated with the HTTP request/response value as a URI.
