var expert1layer="<xsl:apply-templates
select="document(/sco/loadexperts/$expert1id/text" />";


You can't do that, anymore than you can do
"document(/sco/loadexperts/'foo'/text" />"; 

an Xpath is an expression not a string, it would be like saying in C if
you had the string  x= "2 +" could you go y= x 3 and have that evaluate
as y = 2 + 3  and set y to 5.

some systems have an evaluate extension that allows the  evaluation of
strings as xpath expressions (see threads on that over the last couple
of days) then you would do
document(saxon:evaluate(concat('/sco/loadexperts/',$expert1id,'/text')))" />";
but here you can probably just do

select="document(/sco/loadexperts/*[name()=$expert1id]/text" />";

so long as the variable just has an element name not a whole chunk of
xpath.
