+==== Displaying values in a bulleted list ====
+Say we want to display all the authors of a document in a bulleted list. We can't just use <gsf:metadata name="dc.Creator"/> as it will put all the names out in a comma separated list. However, we can use the prefix and suffix options to put some HTML before and after each author.
+<code>
+<ul>
+<gsf:metadata name="dc.Creator" separator=""><prefix><gsf:html>&lt;li&gt;&lt;b&gt;</gsf:html></prefix>
+<suffix><gsf:html>&lt;/b&gt;&lt;/li&gt;</gsf:html></suffix></gsf:metadata>
+</ul>
+</code>
+This will produce output like:
+<ul><li><b>John Smith</b></li><li><b>Katherine Don</b></li><li><b>Cliff Richard</b></li></ul>
+==== Linking metadata to a search ====
+How to link metadata values to a search for that value?
-How to link metadata values to a search for that value.
 For example, say a document has several authors, stored as dc.Creator metadata. You can display a list of the authors, each one linked to a search of the dc.Creator index for that author.

 Greenstone provides a shorthand: **<gsf:html>"</gsf:html>**, which gets resolved to <xsl:text> with the disable-output-escaping attribute set.
