workaround for xpath 2.0 exists() function?

Having finally discovered that exists() is a xpath 2.0 function is there a
work around?

For example, I want an expression that will select <aaa> elements that do
not have children containing <aaa> tags

<aaa>
<aaa>
<aaa/>
</aaa>
<aaa> // this node wanted
<bbb/>
</aaa>
<aaa> // this node wanted
<ccc/>
</aaa>
</aaa>

I think the following should work

//aaa[exists(child::*) = true() and exists(child::aaa)=false()]

Can this be done in xpath 1.0?

NB. I tried using count() but count returns zero whether or not a child node
exists

Maybe,

aaa[* and not(aaa)]
