This is regular expression. ? makes the pattern in () optional. To explain it further, if you use "?",  all paths under /content are valid(including /content as well) but if you dont use "?" then "/content" is not allowed.

/content [Invalid when "?" is NOT there]

/content/a [Valid in both]

/content/a/b [Valid in both]

    That's the defined regex which matches to the page path for template availability at a path.
