Write a validation formula as follows:

count(xxf:split(.)) le 3

This tokenizes the space-separated values selected by the checkbox. If you count the tokens, you find the number of selected checkboxes. Then this makes sure the number of tokens is lower than or equal to 3.

I also added this to the list of examples.
