The new JAXP redirection (MODULES-338) requires resources which are string-backed. Instead of using a proprietary string URL scheme, it would be better to just provide proper support for data URLs via a URLStreamHandlerFactory.
Requirements:
- Conform to RFC 2397, which means:
- Support for base 64 content using MIME decoding (with whitespaces stripped out)
- Support for non-base 64 content using URL decoding with the proper charset
- Support for charset specification (default to US-ASCII) by way of the charset parameter; invalid charsets should result in UnsupportedEncodingException
- Return the URL content type from URLConnection#getContentType() which should include all parameters given as part of the URL except for base64, with the special exception that text/ media types should have the charset as the first parameter, and charset should be excluded from other types; the default media type is text/plain
- Other well-formedness errors should result in ProtocolException

The obsolete urlchar production is closest to uric from RFC 3986:
