Thanks, I see a lot of this is in the XDM spec... (which I've never
had the pleasure of reading until now)

The key sections are:
http://www.w3.org/TR/xpath-datamodel/#TypedValueDetermination

and:
http://www.w3.org/TR/xpath-datamodel/#const-psvi-element
(type-valued section heading)

Out of interest, what is the reasoning behind allowing a mixed content
element's typed-value to be its string value, but making it an error
for element-only content?

Is it that you can't guarantee to get a string from element only
content, but mixed content you can (somehow) ?

thanks
