-<!--why is this in gcpm-->
-Many documents contain internal references:
-<ul>
-<li> See chapter 7 </li>
-<li> in section 4.1 </li>
-<li> on page 23 </li>
-</ul>
-Three new values for the content property are used to automatically create these types of cross-references: ''target-counter()'', ''target-counters()'', and ''target-text()''. Each of these displays information obtained from the target end of a link.
-<h3 id="target-counter">
-The ''target-counter()'' function
-</h3>
-The ''target-counter()'' function retrieves the value of the innermost counter with a given name. The required arguments are the url of the target and the name of the counter. An optional counter-style argument can be used to format the result.
-
-
-<p class="note">These functions only take a fragment URL which points to a location in the current document. If there’s no fragment, if the ID referenced isn't there, or if the URL points to an outside document, the user agent must treat that as an error.</p>

-This functions fetches the value of all counters of a given name from the end of a link, and formats them by inserting a given string between the value of each nested counter.

-The ''target-text()'' function retrieves the text value of the element referred to by the URL. An optional second argument specifies what content is retrieved, using the same values as the 'string-set' property above.
