I haven't followed the thread, but...

In XSLT 1.0, applying count() to anything other than a node-set is an error
(one of the very few dynamic errors defined in XPath 1.0). It's being
applied here to a boolean.

In XSLT 1.0, applying count() to a boolean always returns 1.

So the statement doesn't look correct at all.

Perhaps (count(b[not(c)]) &gt;= 1) was intended.
