No, the term "set" is used loosely here to mean "collection". I will
change it.

Subject: [xsl] xslt2 grouping


http://www.w3.org/TR/xslt20/#d5e12772 says

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.
A set.
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?

TIA, DaveP.
