+/*! \brief A wrapper around a Matrix URI or identifier
+ *
+ * This class encapsulates a Matrix resource identifier, passed in either of
+ * 3 forms: a plain Matrix identifier (sigil, localpart, serverpart or, for
+ * modern event ids, sigil and base64 hash); an MSC2312 URI (aka matrix: URI);
+ * or a matrix.to URL. The input can be either encoded (serverparts with
+ * punycode, the rest with percent-encoding) or unencoded (in this case it is
+ * the caller's responsibility to resolve all possible ambiguities).
+ *
+ * The class provides functions to check the validity of the identifier,
+ * its type, and obtain components, also in either unencoded (for displaying)
+ * or encoded (for APIs) form.
