// metaversion 1.0
// ===============
//
// Added as child of <linden_genepool>:
//
//   <meta gridnick="secondlife" date="2013-07-16T16:49:00.40Z" />
//
// Optionally, as child of <archetype>, the following node may appear:
//
//   <meta path="clothing/jackets" name="Purple jacket" description="A jacket with mainly the color purple" />
//
// Furthermore, metaversion 1.0 and higher allow the occurance of one or more <archetype> blocks.
// If this is used then it is strongly advised to use one <archetype> per wearable, so that
// the the <meta> node makes sense (it then refers to the wearable of that <archetype>).
//
// The reason for this clumsy way to link wearable to extra meta data is to stay
// compatible with the older format (no metaversion).
