Yep, that should be 77 and the XEP should explicitly state that the end 
index is exclusive (while the start index is inclusive). Together with 
the numbering being zero-indexed, this would be similar to the behavior 
of APIs like Android's android.text.Spannable.

While at it, the textual <body/> content of the examples in the XEP 
should be way shorter. And it should be explicitly explained which part 
of the text is referenced, e.g.:

Text is spantastic!
