Attribute order recommendations

Folks,

Understanding XSLT as quick as possible is important. This blog post with the
motto "Spare the maintainer" impressed me some years ago:

But what about attribute order conventions?

I started putting the typing attribute as="b&" at the end of e.g.
xsl:variable, xsl:function or xsl:param.

But then I meet tunnel="yes", shall I put it before as="b&" or at the very
end, to make it more obvious to the casual observer?

Also, in a recent post by Graydon Saunders I notice as="b&" as the very first
attribute on every xsl:variable, even before name="b&" which also makes sense
to me somehow.

Have I missed some insightful source/post, or can we discuss the benefits of
attribute order conventions?
