Thats what I did before. Thats what I thought I did again and to be
doubly sure I cut and pasted from your post.

I get

<switch xmlns="http://www.w3.org/2002/xforms">
<case id="sales stocks plants clientsCase">
*************************the id attribute is wrong
*******************************
<b2b:Sales xmlns:b2b="http://www.b2b.net/plants">
<xf:bind repeat="saleBindings.xml"/>
</b2b:Sales>
<b2b:Stocks xmlns:b2b="http://www.b2b.net/plants">
<xf:bind repeat="stockBindings.xml"/>
</b2b:Stocks>
<b2b:Plants xmlns:b2b="http://www.b2b.net/plants">
<xf:bind repeat="plantBindings.xml"/>
</b2b:Plants>
<b2b:Clients xmlns:b2b="http://www.b2b.net/plants">
<xf:bind repeat="clientBindings.xml"/>
</b2b:Clients>
</case>
</switch>

I should add though  I am running this in eXide maybe Saxon would give
me a different result.
