I could be reading it wrong, but I don't think that section covers the

I believe it is covered by the very first sentence of 5.8, even though
there isn't an example of the processing of leaf nodes in a mode.
There cannot be a situation where there is no template anywhere for any
mode, so the first sentence implicitly includes processing leaf nodes in a
mode.
5.8 starts: "There is a built-in template rule to allow recursive
processing to continue in the absence of a successful pattern match by an
explicit template rule in the stylesheet." ... therefore if the stylesheet
is absent a successful pattern match for a text node in a mode, there must
be a built-in template rule. And the built-in template rule for text nodes
adds the node to the result tree. I think it is just missing detail to
spell that out in the document.
I would expect this stylesheet:
<?xml version="1.0" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; >
<xsl:template match="/">
<MISSING_MODE>
<xsl:apply-templates mode="MISSING_MODE"/>
</MISSING_MODE>
</xsl:template>
</xsl:stylesheet>
to output:
<MISSING_MODE>
</MISSING_MODE>
That would require an empty template rule for the text() node .. not an
absent template rule. I don't think an absent rule should imply "do
nothing", therefore, I think the spec successfully covers the need for
processing text() nodes in any mode by adding their content to the result tree.
Both Xalan and Saxon behave as though there is a built-in text and
attribute template that is equivalent to:
<xsl:template match="text()|@*" mode="m">
<xsl:value-of select="."/>
</xsl:template>
I believe this to be implied by the first sentence, and I have documented
it as such since day one in my XSLT training material, and I chose to
include in the material an illustration of the template rules for leaf
nodes in a mode.
