RFC 5545, "Internet Calendaring and Scheduling Core Object Specification (iCalendar)", September 2009

Errata ID: 5602
Status: Reported
Type: Technical
Publication Format(s) : TEXT
Reported By: Carsten Bormann
Date Reported: 2019-01-15

Section 3.1.3 says:

     ATTACH;FMTTYPE=text/plain;ENCODING=BASE64;VALUE=BINARY:VGhlIH
      F1aWNrIGJyb3duIGZveCBqdW1wcyBvdmVyIHRoZSBsYXp5IGRvZy4

It should say:

     ATTACH;FMTTYPE=text/plain;ENCODING=BASE64;VALUE=BINARY:VGhlIH
      F1aWNrIGJyb3duIGZveCBqdW1wcyBvdmVyIHRoZSBsYXp5IGRvZy4=

Notes:

The base64 text used in the example misses the base64 padding. RFC 5545 appears to be using base64 according to RFC 4648 Section 4 with padding throughout, except for this example. (The corrected text decodes to "The quick brown fox jumps over the lazy dog.") Beyond temporary confusion in implementers, it is possible that this example will turn up in a test suite and ultimately cause unnecessarily lenient behavior of decoders ("soup"); it should be either clarified that this lenient behavior is not the intention or the behavior should be codified.
