Hi Johannes,

You could define the syntax for has_integral to be literally

   "(f Bochner.has_integral x) s"

and similarly for the other. Additionally, you could declare bundles with the existing 

   "(f has_integral x) s"

for both of them (like is nowadays done for the Lifting package syntax). Then, you can 
locally include the notation for the desired integral with "includes", which is more 
flexible than a locale interpretation.
