Type of schema.org/Text, and limitations of same

Reading the implied restrictions on microdata, which schema.org operates
in, I assume any property with type Text is supposed to be non-HTML and
specifically limited to the results of "innerText" in the DOM.  If this is
a correct interpretation:  How would one handle standard bold, italic, etc.
markup inside properties such as articleBody (http://schema.org/Article)?
 This seems like a fairly major limitation, in that receivers don't even
necessarily have access to the original HTML content in order to perform
their own transformations or sanitization.
