Don't check that the flow impl kind matches the flow spec kind when the
flow spec cannot be resolved.
Don't check the type of a FlowSegment if the context or flowElement
could not be resolved.

Fixed an error in the check for flow connection order.
Allow a subcomponent flow to refer to a local or inherited data access,

Don't do type checking when linking a FlowSegment's context.  Link any
visible Context and let the validator do the type checking.
Don't do type checking when linking a FlowSegment's flowElement.  Link
any visible FlowElement and let the validator do the type checking.
Created a validation test for the type checking of a FlowSegment.
