Further to our discussions on numbers, I have added the following to feature_system.xml

1) wordType numberStem. So ECH will add this <fs> to the number stems 1-10.

<fs>
<f name="numberStem">
<binary value="true"/>
</f>
</fs>

2) countingType "ten"

I have also added the following <fs> to lexical suffix "akst-2", so ECH can use this morpheme for marking up the numbers 30, 40 ... 90.

<fs>
<f name="baseType">
<symbol value="affix"/>
</f>
<f name="positionType">
<symbol value="suffix"/>
</f>
<f name="affixType">
<symbol value="derivational"/>
</f>
<f name="derivationalType">
<symbol value="lexical"/>
<symbol value="counting"/>
</f>
<f name="countingType">
<symbol value="ten"/>
</f>
</fs>

MDH will then search for entries with this <fs> to build a test column for the table of numerical expressions. We can subsequently add more countingType values to the feature system, and to the entries for the appropriate lexical suffixes with classifier functions, and generate more columns for the table.
