I found minor errors on the documentation page of the LessThan constraint. http://symfony.com/doc/current/reference/constraints/LessThan.html

Important here are the first two bullet points of the "Basic Usage" chapter, which currently look like this

• The first bullet point contains information which should be only present in the LessThanOrEquals Constraint
• The second bullet point has the number 80, which is not code highlighted, because of a missing space.

I created a PR for this
