Section 3 says:

<Issuer Domain Name> [; <name>=<value> ]*

It should say:

<Issuer Domain Name> [; [ <name>=<value> ]* ]

Notes:

For values of the "issue" and "issuewild" property tags, section 3 specifies [; <name>=<value> ]* (which seems to indicate that every parameter is preceded by a semicolon) but the grammar in section 5.2 specifies [";" *(space parameter) space] (in which parameters are separated by whitespace and the entire list is preceded by a single semicolon). Presumably, the formal grammar is definitive and the preceding shorthand should be updated to better express it.
