    // If |is_standard| is true (1) the scheme will be treated as a standard
    // scheme. Standard schemes are subject to URL canonicalization and parsing
    // rules as defined in the Common Internet Scheme Syntax RFC 1738 Section 3.1
    // available at http://www.ietf.org/rfc/rfc1738.txt
    //
    // In particular, the syntax for standard scheme URLs must be of the form:
    // <pre>
    //  [scheme]://[username]:[password]@[host]:[port]/[url-path]
    // </pre> Standard scheme URLs must have a host component that is a fully
    // qualified domain name as defined in Section 3.5 of RFC 1034 [13] and
    // Section 2.1 of RFC 1123. These URLs will be canonicalized to
    // "scheme://host/path" in the simplest case and
    // "scheme://username:password@host:port/path" in the most explicit case. For
    // example, "scheme:host/path" and "scheme:///host/path" will both be
    // canonicalized to "scheme://host/path". The origin of a standard scheme URL
    // is the combination of scheme, host and port (i.e., "scheme://host:port" in
    // the most explicit case).
    //
    // For non-standard scheme URLs only the "scheme:" component is parsed and
    // canonicalized. The remainder of the URL will be passed to the handler as-
    // is. For example, "scheme:///some%20text" will remain the same. Non-standard
    // scheme URLs cannot be used as a target for form submission.
    //
    // If |is_local| is true (1) the scheme will be treated as local (i.e., with
    // the same security rules as those applied to "file" URLs). Normal pages
    // cannot link to or access local URLs. Also, by default, local URLs can only
    // perform XMLHttpRequest calls to the same URL (origin + path) that
    // originated the request. To allow XMLHttpRequest calls from a local URL to
    // other URLs with the same origin set the
    // CefSettings.file_access_from_file_urls_allowed value to true (1). To allow
    // XMLHttpRequest calls from a local URL to all origins set the
    // CefSettings.universal_access_from_file_urls_allowed value to true (1).
    //
    // If |is_display_isolated| is true (1) the scheme will be treated as display-
    // isolated. This means that pages cannot display these URLs unless they are
    // from the same scheme. For example, pages in another origin cannot create
    // iframes or hyperlinks to URLs with this scheme.
    //
    // This function may be called on any thread. It should only be called once
    // per unique |scheme_name| value. If |scheme_name| is already registered or
    // if an error occurs this function will return false (0).
