Hi Manfred,
This is a bit of an xproc gotcha. When you move the <p:input> inside
the <p:add-attribute />, there's no longer a default readable port to
provide context for the xpath in p:with-option/@select. When you were
using a p:identity, its output provided the needed context for
p:with-option/@select.
You need to change your p:with-option to read:
<p:with-option name="attribute-value" select="$dir" >
<p:empty />
</p:with-option>
A previous discussion can be found here:

Hope this helps,
-James
