[xsl] Re: XSLT 3.0: The definition of the "unnamed mode"

> 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:

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."

Yes, this is precise.
