i'll have to read about templates with mode attributes, never saw them.
I tell my students to just think of the mode attribute values as names of
collections of template rules. You need to name the collection you want
applied when you use <xsl:apply-templates> and you need to name which
collection a template rule is in when you declare <xsl:template>.
Up until now you've been using the unnamed collection of template rules,
and now you know how you can create named collections of template rules.
Think of the utility of this when you have to do, say, three passes on data
to produce a book: one for the table of contents, another one for the body,
and yet another one for the index. If it was only possible to have one set
of template rules, the logic inside would be horrendous trying to determine
what state you were in. Instead, one creates three collections of template
rules (one of which may be unnamed) and you just, in turn, use each of the
collections.
Quite powerful.
I hope this helps the understanding.
