Description

When trying to load a registry resource as XSLT source, XsltUriResolver uses ResourceHelper to check the scheme and then load the resource.

ResourceHelper.hasScheme(String) only supports "file:", "classpath:", "http:" and "https:" schemes, so the "ref:" uri fails to validate and is not correctly handled (the prefix "classpath:" is automatically appended).

The resulting exception when using a "ref:" uri is the following:

javax.xml.transform.TransformerException: java.io.FileNotFoundException: Cannot find resource: classpath:ref:camelResource-2 for URI: classpath:ref:camelResource-2
