  // Register a custom scheme. This function should not be called for the built-
  // in HTTP, HTTPS, FILE, FTP, ABOUT and DATA schemes.
  //
  // 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 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 can only be displayed from
  // other content hosted with the same scheme. For example, pages in other
  // origins cannot create iframes or hyperlinks to URLs with the scheme. For
  // schemes that must be accessible from other schemes set this value to false
  // (0), set |is_cors_enabled| to true (1), and use CORS "Access-Control-Allow-
  // Origin" headers to further restrict access.
  //
  // If |is_secure| is true (1) the scheme will be treated with the same
  // security rules as those applied to "https" URLs. For example, loading this
  // scheme from other secure schemes will not trigger mixed content warnings.
  //
  // If |is_cors_enabled| is true (1) the scheme can be sent CORS requests. This
  // value should be true (1) in most cases where |is_standard| is true (1).
  //
  // If |is_csp_bypassing| is true (1) the scheme can bypass Content-Security-
  // Policy (CSP) checks. This value should be false (0) in most cases where
  // |is_standard| is true (1).
  //
  // 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).
