RE: [xsl] Count number of specific child templates

["Michael Kay" <mike@xxxxxxxxxxxx>]

What should the result be if <parameters> contains 2 <service1> children and
5 <service2> children?

If the answer is 7, then perhaps you want

count(*[starts-with(local-name(), 'service')])

Generally it looks like bad XML design to have some semantic significance
implied by the fact that <service1> and <service2> have similar names.
Better design would be to use <service nr="1"> and <service nr="2">.
