(see also URIResolver.resolve(String, String)
This resolver will allow URLs without a scheme, i.e. it assumes 'file:' as
the default scheme. It also allows relative URLs with scheme,
e.g. file:../../abc.jpg which is not strictly RFC compliant as long as the
scheme is the same as the scheme of the base URL. If the base URL is null
a 'file:' URL referencing the current directory is used as the base URL.
If the method is successful it will return a Source of type
StreamSource
with its SystemID set to
the resolved URL used to open the underlying InputStream.
