+// portion, the string is interpreted as [userinfo "@"] host [":" port]
+// path-abempty [ "?" query ] [ "#" fragment ] per RFC 3986 [RFC3986].
+// If the userinfo component is present and all of the path component, query
+// component, and port component are empty, the acct scheme is assumed. In this
+// case, the normalized URI is formed by prefixing acct: to the string as the
+// scheme. Per the 'acct' URI Scheme [I‑D.ietf‑appsawg‑acct‑uri], if there is an
+// at-sign character ('@') in the userinfo component, it needs to be
+// percent-encoded as described in RFC 3986 [RFC3986].
+// For all other inputs without a scheme portion, the https scheme is assumed,
+// and the normalized URI is formed by prefixing https:// to the string as the
+// scheme.
+// If the resulting URI contains a fragment portion, it MUST be stripped off
+// together with the fragment delimiter character "#".
+// The WebFinger [I‑D.ietf‑appsawg‑webfinger] Resource in this case is the
