[xep-support] Need to evaluate string-lengths for a set of nodes--how?

[Blankner, Sherrod]

	Can anyone out there help me brainstorm some logic for a letter
recipient name:

	We have a simple letter XSL that processes the following XML to fill
in the recipient name
	<names>
		<name>John Doe</name>
		<name>Jane Doe</name>
		<name>Jim Doe</name>
		</names>

	Currently our XSL is very straight forward

			<fo:block>
				<xsl:for-each select="names/name">
					<fo:block>
						<xsl:value-of select="."/>
					</fo:block>
				</xsl:for-each>
				</fo:block>


However, with the new window size in the envelope, we can't stack names
indefinitely--we only have 6 lines for the total address, with a maximum of
three name lines if the address is in the US. I need logic that evaluates
whether the string length of a set of <name> tags is more than 61
characters, at which point I want to cut off and print just those names into
line 1. Then I need to start where line 1 left off and evaluate the next set
of <name> tags and see if these add up to under 61 characters, at which
point I can write in line 2, etc. I have three possible lines.

Does anyone have any suggestions?
I've been working with the string-length function, but I can't seem to get
it to increment up inside a for-each loop. I also messed around with some
param/call-templates functions but got the same result. 

Thanks
Sherrod
