                    to store metadata for an item.  When that metadata is
                    structured as an item, there needs to be a way to

Comment:
In HTML, the content of the meta tag is empty, however, it also serves the
dual purpose of being able to store metadata for an item.  When that metadata
is structured as an item, there needs to be a way to include further meta tags
within the original meta tag to reproduce the structure.  This could be
handled with itemref attributes pointing to the id for subsequent meta tags,
but it would be simpler to allow meta to contain other meta tags.

An example of where this is easier is when converting from an existing XML
structure using XSLT recursively.  A simple solution to convert an XML tree
into microdata (when there is no associated text content) is to generate a
meta element where itemprop='element-name' and content='element-value', and
where there is nested elements or attributes, to process those as inner (meta)
children of the outer meta element.
