[Xsltforms-support] access to user selection?

[C. M. Sperberg-M. <cm...@bl...>]

Is there any way, in XSLTForms, to get access to the string of
characters the user has selected with a mouse? 

For example, imagine an xf:input bound to a PCDATA element,
in a mixed-content document.  The user would like to tag
some part of the text with a sub-element, e.g. to change

  <p>Nobody does humility better than me.</p>

to 

  <p><emph>Nobody</emph> does humility better than me.</p>

I have in mind a display of the text node, followed by a button
reading (say) "Tag selected text as 'emph'".

Possible?  Possible without writing functions in Javascript? 
Not possible?

best,

Michael

p.s. Yes, I am aware of the TinyMCE editor; I am trying to see how
far one can go without it or something analogous.  (And the last
time I tried, I couldn't get TinyMCE to do what I wanted.  I'll
try again sometime, but my question remains.)
