=== epc:print ===

 <epc:print expr='expression' opt='key=value;key2=value2'/>
<source lang="xml">
 <cite:citation xmlns="http://www.w3.org/1999/xhtml"
           xmlns:cite="http://eprints.org/ep3/citation"
           xmlns:epc="http://eprints.org/ep3/control">
     <epc:print expr="$item.citation('default')" />
 </cite:citation>
</source>
Outputs the result of the expression in the 'expr' attribute. 

Rendering options may be passed in the opt attribute using a key=value form, with semicolons separating multiple options.

Any [[EPScript]] expression can be used. The most simple is just 'eprintid','title','creators' etc. You can also use values from the configuration files by using '$config{base_url}'.

=== Print in attributes using {} ===

Sometimes you may wish to insert a value into an XML attribute. eg. the "href" part of an anchor. Rather than a complicated system, but correct XML, we decide to go for something a bit more readable. Any {} pair in an XML attribute will be treated as a epc:print.

So you can do something like 
<source lang="xml">
<a href="http://eprints.badger.edu/cgi/myscript.pl?eprintid={eprintid}">run myscript on this eprint</a>
</source>

=== epc:phrase ===

simple:
<source lang="xml">
 <epc:phrase ref='phraseid' />
</source>
with pins:
<source lang="xml">
 <epc:phrase ref='phraseid'>
   <epc:param name='somepin'>Content</epc:param>
 </epc:phrase>
</source>
Outputs the content of the phrase refered to by 'ref'. Any necessary parameters may be set using the <epc:param> tag, with the contents inserted into the pin with the name corresponding to the name attribute.
