     Note: Nonstandard fields should be prefixed by "X-".
 
+    When there are multiple tags with the same name but different values,
+    then each except the first MUST have a sequential number starting at 2
+    appended, for example
+    "Author", "Author2", "Author3", ...
+    This is required to avoid ambiguity when info packets are repeated.
+
+    Subtypes, like the authors email address, MUST have a type that is made
+    of the refering type + '/' + the subtype, so for example 2 email
+    addresses of the second author would be:
+    "Author2/X-EMAIL" and "Author2/X-EMAIL2"
+    All subtags of a tag should be stored immediately after the tag with
+    no other fields in between, so that simple players can just display the
+    tags sequentially and have readable output.
+
+    If the value of a tag is in a specific language, that should be indicated
+    by appending hyphen and the 3 letter ISO 639-2 language code optionally
+    followed by an ISO 3166-1 country code that is separated from the
+    language code by a hyphen as well. Examples would be
+    "Author2-deu" "Michael"
+    "Author2-eng" "Mike"
+
+    names MUST not contain / - or end in numbers to avoid ambiguity.
