<xsl:mode name="x">
   <xsl:template match="a"/>
   <xsl:template match="b"/>
   <xsl:template match="c"/>
</xsl:mode>

is essentially equivalent to

<xsl:mode name="x"/>
<xsl:include href="templates.xsl"/>

where templates.xsl contains the three template rules and specifies
default-mode="x".

There are probably a few minor differences, I wouldn't be 100% confident it's
the same in all edge cases. The main difference is that enclosing modes are
only usable where all the enclosed template rules apply exclusively to that
mode, and all template rules that apply to that mode are enclosed. The main
idea is that you can see "at a glance" exactly what the mode does.
