I have a situation where I want to force a <remove-all> then add the
current value of the attribute on the subscriber channel. We have a
problem when data is out of sync, and we want to force the subscriber to
transfer the value no matter what the value exists in the subscriber
(currently it throws and error)

I don't know squat about stylesheets and it scares me Could someone
help me build one that will:

Match all $Attributes
<add $attribute value>

Thank you for Looking into this!
