Hi Jeremy.
Using the @Annotation designator or, if it is an argument that is annotated, then the @Args, or if it is the target that is Annotated then @Target.
In your case it would be @Annotation, so in your Pointcut Expression you add the @Annotation designator with an "and" or "&&"
so
execution(@com.rbs.etspii.aspects.CheckAssetType com.rbs.base.common.RBSValidationResult submit*(..)) && @Annotation(assetType)"
Now in your advice method you can have the parameter
myAdviceMethod(ResultType result, CheckAssetType assetType)
Like this taken from the SpringFramework documentation
And then the advice that matches the execution of @Auditable methods:
