[xsl] xslt2 grouping
The xsl:for-each-group instruction partitions a sequence into groups of
items (that is, it establishes a set of sequences)
A set of sequences.
But a set does not contain duplicates?
- What definition of duplicate is used please?
say I use group-by="@x"
With two members of the population being
<el x='2' y='3'/> and
<el x='2' y='4'/> are they classed as duplicate members
of this population?
So for our grouping uses, we need to be careful to include
all parts of the population if needed?
Is that right please?
