OASIS XML Localisation Interchange File Format (XLIFF) TC

I am investigating how to carry translation note including link for external materials.
In XLIFF 2.1 specification, <note> element can have optional format style attributes fs:fs ad fs:subFs. And the format style attributes from HTML including many inline elements. However, I have no idea how we can use them in <note>.
 
For example, if you want HTML fragment:
 
  Please check <a href= screen capture</a>.
 
as <note> value, I may put fs:fs attribute like <notes fs:fs="html">, but it looks there is no way to represent inline <a> element in this case.
 
If this is a part of <source> or <target>, I understand it can be represented as below:
 
  <source>Please check <pc id="1" fs:fs="a" fs:subFs="href, http://foo.com/123.jpg ">the screen capture</pc>.
 
But, I don't think <pc> is allowed in <note> value If my understanding is correct.
 
Of course, if we put <a> tag as "&lt;a>" in <note> body, it is valid, but I suspect this is what the spec suggests.
 
  <notes>
    <note fs:fs="html">Please check &lt;a href= screen capture&lt;/a>.</note>
  </notes>
 
Above should be valid, but I think this is not what XLIFF spec author thought about.
Do I misunderstand the specification? If not, what is the typical use case for fs:fs/fs:SubFs attribute in <note> element?
 
Thanks,
Yoshito
