<cache-lookup-value key="@(context.Request.MatchedParameters.GetValueOrDefault("place="""))" variable-name="latlong"/>

It seems that this snippet:

context.Request.MatchedParameters.GetValueOrDefault("place=""") // fails with a missing comma.

whilst using it this way:

context.Request.MatchedParameters.GetValueOrDefault("place", "") // works without an issue.

The other parts where there is a variable with var="" under double quotes, the parser doesn't like much.
