[xsl] What name would you give this function?

["Costello, Roger L." <costello@xxxxxxxxx>]

Hi Folks,

I created a higher-order function.

I will refer to the function as: f

The argument to f  is a sequence of items:

     f (items)

Processing items[1] may produce/generate more items.

After outputting the first item, f is applied to the remaining items plus
g(item[1]), where g is a function applied to the first item.

So, the definition of f is this sequence: items[1],   f(items[position() gt 1]
union  g(items[1])

What name would you call this function? I want something more descriptive than
" f "
