RE: How to not check a textbox if empy

Sure. The assertion test would depend on how the checkbox is represented in 
the XML but if your XML looks something like:

<textbox checkbox="true/false">...value...</textbox>

you can do this with:

<!-- CHECK FOR VALID FORMAT -->
<sch:assert test="@checkbox = 'false' or (...... check format......)">
     <sch:name/> does not contain a valid format.
</sch:assert>

This will only check the value of the textbox if the attribute checkbox has 
a value != 'false'

Cheers,
