I agree, this definition is not a very good one. It's a relic of when the
unnamed mode was always the default mode. A better definition might be:
"There is a mode, called the unnamed mode, that has no name. The properties of
the unnamed mode may be defined using an xsl:mode declaration with an absent
name attribute. The unnamed mode is the default mode for an xsl:apply-templates
or xsl:template element with no mode attribute, unless a different mode is
nominated as the default using an [xsl:]default-mode attribute."

In the 2nd Last Call of the W3C XSLT 3.0 specification, section "6.6.1
Declaring Modes" defines "unnamed mode" thus:
"[Definition: The unnamed mode is the default mode used when no mode
attribute is specified on an xsl:apply-templates instruction or
xsl:template declaration, unless a different default mode has been
specified using the [xsl:]default-mode attribute of a containing
element.]"
I find this definition rather confusing, because the undefined term
"default mode" is used and because this term seems undistinguishable
from two other terms used in the definition: "different default mode"
and "[xsl:]default-mode attribute".
To summarize, this definition seems (endless) recursive, having not
specified the term "default mode" on which it is based.
I believe that a definition that more precisely defines the "unnamed
mode" could be something like this:
1. A mode defined in an xsl:mode declaration (the one with highest
import precedence) that has no "name" attribute specified, or
2. If there is no xsl:mode without a "name" attribute, then a mode
that is defined by an (implicit) xsl:mode declaration without any
attributes.
3. The unnamed mode defined in 1. and 2. above is used as the value of
the "mode" attribute of any "xsl:template" or "xsl:apply-templates"
that have no "mode" attribute specified, unless these are in the scope
of an "[xsl:]default-mode" attribute, in which case the mode specified
in the (innermost) "[xsl:]default-mode" attribute is used as the value
for their "mode" attribute.
Any thoughts, please?
