RE: max() value of cells in a table

xpath max value
I can see the point.
Used in a straight xsl:value-of, it only returns
the first node as per xslt1;
Yet with a name like for.... anything,
its going to be grabbed very quickly by newbies.

In terms of utility, is it the only way to create
a sequence from source content?
That's what I was struggling with.
