#5657 allows "<" in text nodes so that <p>{{ a < b ? c : d }}</p> does not throw.

However this is not valid html - < would have to be < to have a valid html.

One potential issue with the current approach is that in <p>{{ a <b && c > d }}</p> <b && c > would be parsed as an html tag and would not be easy for user to debug.

We could solve this by making the lexer aware of angular expression.

edit {{ "<b>text</b>" }} could also cause pb
