</articles>
#### to navigate trough articles in the default workspace.


####  not default workspace example:

<gallery>
  <param-types child="name" arg="handle" param="type" >
  <param-sample child=name" arg="handle" param="list" refer="types"  />    
  </param-type>
</gallery>



##### where 


 - the node name is the name of the unchained source

- @child:

  the page parameter wich have this value in case of this param is aktive 
  
- @refer [optinal]  
  the child node , a select box link filed is aktiv in case of chained datasources 
  normaly thi is the section name

### unchained datasources output:
  
    </param-navigation-archive>
    <param-navigation-articles>
        <section id="1" handle="articles">Articles</section>
        <entry id="4">
            <title handle="an-example-draft-article">An example draft article</title>
        </entry>
        <entry id="3">
            <title handle="a-primer-to-symphony-2s-default-theme">A primer to Symphony 2's default theme</title>
        </entry>
    </param-navigation-articles 

     in case of one page param to navigate,

     using more param the select box link field must be included
