I'd like to throw in my two cents here.

I know MSXML (and perhaps Saxon and libxslt, I haven't looked into it) offers
a startMode parameter, which allows processing to start in a specified mode.
This is a very useful way to roll several smaller stylesheets into one generic
stylesheet. Is there an easy way to include a switch or parameter like this in
the proposed <xsl:mode> enhancements? As it stands right now, the only way to
specify this is in the processor's implementation.

Note that I'm not trying to tailgate in dozens of additional theoretical "this
might be useful somewhere" requirements a la CSS3. I'm just saying that it's
come across as a basic common-usage requirement in several places in my own
usage, and it'd be great to have it defined in the basic specification
somewhere. :)

The idea is to make modes (the things named in the mode attribute of
xsl:template and xsl:apply-templates) first class objects that can have
properties; the properties would be declared as attributes of an xsl:mode
declaration; one of the properties is the choice of default template rules
for the mode. An xsl:mode declaration with no name attribute declares the
properties of the unnamed ("default") mode, just as an xsl:decimal-format
declaration with no name defines properties of the default decimal-format.

No doubt the choice of keywords will continue to provide entertainment for
some while; I tend to the view that when you hear people arguing the
spelling of the keywords, it's like when a sales prospect starts arguing
about the price; you can smell victory.
