<xsl:for-each select="1 to count($values)"> <xsl:sequence select="$values[current()]"/> </xsl:for-each>
Folks,
Given a variable with a sequence of values
<xsl:variable name="values" select="(1,2,3,4,5)" as="xs:double+"/>
these are three methods to report its content:
<xsl:sequence select="for $i in 1 to count($values) return $values[$i]"/>
<xsl:for-each select="1 to count($values)"> <xsl:sequence select="$values[.]"/> </xsl:for-each>
<xsl:for-each select="1 to count($values)"> <xsl:sequence select="$values[current()]"/> </xsl:for-each>
The first works as expected, the second does not, but the third astonishingly enough gives me the same result as the first. Check it out:

I read/understand that there is a difference between a for expression and a path expression, but since we can use atomized values in xsl:for-each, I would like to see more similarity between for and for-each.
Should this be on the wishlist for XSLT 4 or do I have to learn/understand some more concepts?
Puzzled greeting,
- Michael
