Re: Dynamic numbering of lists in xslt

> I need to use a numberd list but this time using XSLFO and not XSLT.

what do you mean? XSLFO allows the specification of typesetting
properties but has no capability to do any programming of any sort.
The rest of tyour posting consists of some example XSLT stylesheets
(the XSLT happens to use XSLFO literal result elements, but that is 
irrelevant to both the XSLt engine and your problem)

as far as i can tell you want to count travel nodes which have a
location child that matches your params, so use something like

<xsl:number from="/" count="travel1[location/time=$time and location/place=$place]"/>


Do you really want to make a list with one item for each travel element,
why not make a single list outside the code that you have shown and then 
just generate 	<fo:list-item> in the travel1 template.

Your question has nothing to do with xslfo, it's about how to generate
the right number using xslt.
