That does not say the label may consist of "a single" character, but only
discusses the content of the leading character.

1035:

|The labels must follow the rules for ARPANET host names.

|For example, the following strings identify hosts in the Internet:
|
|A.ISI.EDU XX.LCS.MIT.EDU SRI-NIC.ARPA

Does the example override the rule?

Until the 2-char rule inherited from 952 by 1035 is overthrown (which I
wish somebody would state one way or the other), it is implicitly upheld.
