A regular expression element may be followed by a quantifier.
Quantifiers are '*', '+', '?', '{n}', '{n,m}' (and lazy quantifiers
'*?', '+?', '{n,m}?'). There's nothing in the regex language which says
you can follow an element with two quantifiers.
In fact, *you* did -- the first sentence of that paragraph! :-)
\s is a regex, so you can follow it with a quantifier and get \s{6}.
That's also a regex, so you should be able to follow it with a
quantifier.
OK, I guess this isn't true... you said a "regular expression *element*"
can be followed by a quantifier. I just took what I usually see as part
of a regular expression and read into your post something it didn't
quite say. Still, the rest of mine applies.
