The "correct" way to do this is to specify a case-blind collation, for
example

<xsl:for-each-group ...
collation="http://saxon.sf.net/collation?ignore-case=yes"

Unfortunately however collation URIs are not standardised: the above URI is
specific to Saxon, and you will have to to some research to discover whether
equivalents are available with other XSLT 2.0 processors. So a more
pragmatic solution might be to use

group-by="upper-case(EXP)"

where EXP is your grouping key. This will work well enough in most
situations, certainly for the English alphabet.
