==========

This XSLT stylesheet transforms the cmark XML format back to Commonmark.
Since the XML output is lossy, a lossless MD->XML->MD roundtrip isn't
possible. The XML->MD->XML roundtrip should produce the original XML,

// This is a sketch of how to make caching of Ruby objects work with
// Ruby's GC under Clownfish. We use a registry that keeps a list of all
// Ruby objects created from Clownfish. This list is walked during GC to
// mark all objects with a positive Clownfish refcount and prevent them
// from being destroyed if all references from Ruby space were dropped.
//
// Once a Clownfish object has been passed to Ruby, it lives on even with
// a zero Clownfish refcount. This means that there are no more references
// from Clownfish but possibly from Ruby space. The Clownfish refcount
// might even become positive again if an object is passed back to
