'/' is critical to make the thing work because it is the element
separator. '*', '(', '|', and, ')' would be nice to disallow but are not
critical.

I am fine with this if it can be implemented by adding another
constructor to the NodeContainer class:
class NodeContainer {
public:
  NodeContainer (std::string name);
};
and maybe, if needed:
  NodeContainer (const char *name);

Otherwise, I would be scared by the idea of adding yet another set of
overloaded Install methods.
