Figure Reference in Text

Hi All,

What is the 'proper' way to mark up the figure reference ('Figure 1' 
below) and the caption text which occurs in the text?

I simply inserted a <para> child into <caption> to house the text.  The 
<link> functions correctly in both HTML and PDF output.

One other question is how can I color the link in the PDF output? 
Currently it is rendered in the same black color.

For example,

  This is the first sentence.  This is the second sentence, so now 
please look at <link linkend='fig 1'>Figure 1</link>.  This graphic is 
a pretty picture of a circle. Many more sentences follow

                 <mediaobject id='fig 1'>
                         <imageobject>
                                 <imagedata 
fileref="/Samples/circle.jpg"/>
                         </imageobject>
                         <caption>
                                 <para>
                                  Figure 1. A circle which is used 
purely as example
                                 </para>
                         </caption>
                 </mediaobject>


This is the next sentence. And so on and so on.

---------------------  End sample  ------------------------------
