## Action
= Action XSLTs Unique Subjects =

Part of [[Iteration8| iteration 8]].

## Detailed description of wanted output from the work to be carried out.
## E.g. Implement a utility class for writing data to a disk. The data must be base64 encoded before being written.

Currently the index XSLT collects all subjects from all objects considered part of this index representation. This means that some subjects are repeated a large number of times in the index document and presentation. We want the XSLT to make sure that each subject is unique.

Here is something for inspiration:

{{{
<for-each select="$nodes">
  <variable name="node" select="item/text()"/>
  <if test="not(following::item[text()=$node])">
     ... do the output ...
  </if>
</for-each>
}}}

This will select unique text, under $nodes in elements called "item".

This must be incorporated in the indexing xslt document (subjects may not be the only thing) and the presentation xslt document.

This must be tested to behave as expected.

Estimated 1-2 md.
