Used in a straight xsl:value-of, it only returns
that's a feature of xsl:value-of not of for though.
value-of returns the string value of its argument so you never get a
sequence. If you use the xslt2 separator attribute on it though you at
least get the string value of all the terms, separated by whatever you
specified.
In terms of utility, is it the only way to create
a sequence from source content?
no, you could schema-type the content of an element to be a list type,
then you'd get a sequence directly.
all path expressions like /a/b/c return sequences in xpath2 as node sets
are no more.
but for is the main operation in xquery, taking on the roles of
xsl:for-each and xsl:apply templates, and Xpath2's for is a cut down
version of that, so is in some sense the main sequence mapping operation
in the current drafts.
