For now, in such case, what follows is the best you can do:
---
elem {
display: block;
margin-left: 50;
collapsible: yes;
collapsed-content: "--- elem ---";
}
elem:before {
content: collapser();
display: marker;
}
---
If you can program in Java, you could replace "--- elem ---" by
something smarter. See
http://www.xmlmind.com/xmleditor/_distrib/docs/dev/ar01s07.html
And, in the near future, you'll be able to replace "--- elem ---" by an
XPath expression using the target of the CSS element as a context node
(which can be used to quickly and easily do what you want).
