In XSLT 1.0 this should give you an error: the argument of count() must be a
node-set, not a boolean. (It's actually one of the few type errors you can
get from XSLT 1.0).

In 2.0 the count() of a boolean value is always one (a single value is a
sequence of length one).

I don't know what result you wanted: perhaps

 count(*[starts-with(name(),'DGBUIMSNNumber')][@action='add'])
