Hi Dave,

I figure if you consider JSON to be a set of name-value pairs of the form:

    name : value

then the equivalent form for XML elements is:

    <name>value</name>

Therefore a value of type marked-up text ought to correspond to the 
'content' production in XML, which is:

[43]    content    ::=    CharData? ((element | Reference | CDSect | PI | 
Comment) CharData?)*

i.e., it needn't start with a start tag.

Also, if you require an initial start tag, then you are effectively doing:

    name : <name>value</name>

giving an additional XML name to the value that already has a name from 
JSON, which seems redundant.

I suppose yet another way to look at it is, is the 'value' simply 'marked-up 
text' (which in simple cases could actually be text with no markup at all) 
or is it 'XML text'?
