[xsl] Case-insensitive filter match for template wanted

["Kerry, Richard richard.kerry@xxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I have a template for which I need it to do a case-insensitive match on a
value in an attribute.

When my template's filter was case-sensitive it worked happily.
Ie.
<x:template match="section[ parameter/@name='Rule' ][ parameter/value/@entry =
'INPUT' ]" mode="processes" >

Each 'section' has multiple child 'parameter' elements, each containing
multiple 'value' elements.
It turns out that the @entry attributes have variable case.
So I tried:
<x:template match="section[ parameter/@name='Rule' ][ upper-case(
parameter/value/@entry ) = 'INPUT' ]" mode="processes" >

But that gives me (using Saxon HE9.7.0.5):
bA sequence of more than one item is not allowed as the first argument of
upper-case() ("INPUT", .....b

Ok, I can see that is telling me I'm expecting too much from the system and it
can't do the template match with the upper-case function applying to all the
possible parameter/value/@entry values.

Can anyone advise how I can get behaviour equivalent to this.

I hope the above is clear - in natural language what I want is
match any 'section' element
  where
    there is a child 'parameter' element whose '@name' attribute is 'Rule'
  and
    that child 'parameter' element has a 'value' element whose '@entry'
attribute is 'INPUT' (or 'input' or 'Input' etc)

Regards,
Richard.
