[xsl] Add element at the end of a variable group of elements

Hi all,

Using XSLT 2.0, I'd like to add an element at the end of a group of elements 
that may vary whether they exist. 

This seems like a classic case that people have to deal with all the time, but 
I've searched without luck, and I'm on maybe lesson 4 of ??? of the online XSLT 
course I've been taking for the past decade.

So, given the XML

<root>
   <foo/>
   <bar/>
   <mercury/>
   <venus/>
   <earth earth-type="round"/>
   <earth earth-type="flat"/>
   <mars/>
</root>

I want to add <moon>Now with more craters!</moon> after the <foo>, <bar>, 
<mercury>, <venus> group of elements and before the <earth>, <mars> group of 
elements, BUT I only know for sure that <foo> and <mars> will exist in the 
input XML. All the others are optional.

In the Oxygen XPath test window, "root/(foo|bar|mercury|venus)[last()]" got me 
where I wanted to be, but alas, parentheses are not allowed in the @match for 
the template. 

Thanks!
Charles
