    Description copied from class: StreamingAdjunct
    
    Compute the posture and sweep of this expression as defined in the W3C streamability specifications. This must be implemented in all subclasses that don't use the general streamability rules. The implementation should have the side-effect of computing the streamability of all subexpressions, recursively.
    
    Overrides:
    
    computeStreamability in class StreamingAdjunct
    
    Parameters:
    
    contextInfo - Information about the context item type and posture
    
    reasons - the caller may supply a list, in which case the implementation may add to this; the contents are human-readable messages explaining why the expression is not streamable.
    
    Returns:
    
    the posture and sweep of the expression
