Noted mkii and mkiv versions
=== Flashcards ===
For tests and vocabulary it is usefull useful to use flashcards for learning. (This version is for mkii. See below for mkiv)

=== Dictionary entries in XML-format ===
Just a example how to use XML to store and access information.
In my example the content for the dictionary is stored in a buffer,
to use a external file for the data the commented lines for MkII
and MkIV are required.
<texcode>
% engine=pdftex
\startbuffer[lexicon]
</texcode>
<xmlcode>
<lexicon>
<entry name='LaTeX'>
<name>&latex;</name>

This is the MkII code to process the data above.

In MkIV we have direct access to the data can process the content
without the previous step to save everything in macros.
