Here, ALPHA, unreserved and pct-encoded are as defined in 3. "base64url" is defined as in 4 with padding omitted. (Note that this uses a different alphabet to the usual base64; the values 62 and 63 in the alphabet are encoded as - and _ respectively. Implementations MUST NOT accept the characters +, /, and = that occur only in the usual base64.)

Productions of the form 1*x indicate one or more successive instances of the production x. Productions of the form <n>*<m>x indicate at least <n> and at most <m> instances of production x.

Note that this grammar does not allow percent encoding outside the productions that use qchar, i.e. the values of label, message, reqparam, and otherparam parameters.

Purported ZIP 321 URIs that cannot be parsed according to the above grammar MUST NOT be accepted.

URI Semantics

A ZIP-321 URI represents a request for the construction of a transaction having one or more payments. In the case that only a single payment is being requested, the recipient address SHOULD be included in the hier-part component of the RFC 3986 URI; otherwise, multiple recipient addresses can be specified using addrparam parameters with different indices.

Invalid; percent encoding is only allowed in qchar productions, which do not include addresses, amounts, or parameter names.

Invalid; the grammar does not allow //. ZIP 321 URIs are not "hierarchical URIs" in the sense defined in 3 section 1.2.3, and do not have an "authority component".
