I'd not say you're correct, and I'd shy away from speaking about
*the* "standard", whatever you mean by that. Where there's two kinds
of regular expression, claiming that one is standard implies the other
is not, forcing upon it gratuitous negative connotations. If you do
feel the urge to think in terms of standard/non-standard, don't think
of there being one standard and one non-standard but rather of there
being two standards.

You pays your money and you takes your choice.
