Resolve relative URIs against the static base.

[cfoster]

The implementations of the applier functions create an InputSource containing the relative URI as a systemId, which although is common practice, is against the contract for InputSource.setSystemId() -- "If the system identifier is a URL, it must be fully resolved (it may not be a relative URL)."

Action

To resolve href against static base in extension function, override supplyStaticContext() in the implemenations of ExtensionFunctionCall - and capture the value of staticContext.getStaticBaseUri().
