Yes, the select attribute is important. Thanks for reminding this.

Yes, if we know (or it is guaranteed) that only one template is in the
mode "foo", then

<xsl:apply-templates mode="foo"/>

is in "pull style" as we exactly know what particular template will be
selected for processing (as there is only one such template).

One could argue that even if this guarantee doesn't exist we still
have "push style" here. For me it is not "pure push style" if you are
not 100% sure which template will be selected for processing (and this
is the case when more than one templates could be selected: which one
depends on the individual nodes in the current node-list.

When we know that only one particular template will be selected for
processing and we know exactly which it is, then we "are in full
control" and this is "pull style" processing.
