> It failes at the position @. But why?

you can't just put an axis (or an abreviated  axis such as @) straight
after a predicate: you have to separate steps in an XPath expression
with / so its
...] / @...
not
...]  @...

so
<xsl:when test="//*[contains(name(),'DebtManagement') and
(//*[contains(name(),'DebtManagement')]/@action='add' or
//*[contains(name(),'DebtManagement')]/@action='delete')">

is legal but doesn't test what you want to test.

(do you really want to use // it's very expensive operation: searching
the whole document to arbitrary depth)

"//*[contains(name(),'DebtManagement')
finds the elements you want but then (I think) you want to know if
_those_ elements have an add or delete action, but your test just
searches the entire document again (twice) finding the same eleemnts
each time.

I think you want

//*[contains(name(),'DebtManagement')[@action='add' or @action='delete']

But if you can use something other than // it is likely to be more
efficient. Or you could use a key.
