CSS class repetition to increase specificity

According to the CSS docs: http://www.w3.org/TR/CSS21/cascade.html#specificity

Specificity is defined by (amongst other things) the number of attributes and pseudo-classes in the selector.

So, my question is, is it possible to increase specificity by repeating the same classname over and over again?

For instance:

would

.qtxt.qtxt.qtxt.qtxt.qtxt
{
}

have a higher specificity than

.qtxt.lalgn
{
}

or

.lalgn .qtxt//(space added to create child selector)
{
}

?
