                   ^^^^^^^^

There is your problem: you have a relative XPath expression.  The first 
for-each evaluates its expression in the context of whatever node you 
selected outside the for-each, presumably a univ-xml-list from your example.  
The second for-each is evaluating its expression in the context of what was 
selected from the first for-each, which is 
"/university-records/univ-ids/univ".  For this to work, the document loaded 
by the first document() would have to look like this:

<university-records>
  <univ-ids>
    <univ>
      <univ-xml>ignored</univ-xml>
      <univ-xml>this is univ-xml[2]</univ-xml>
</>

I'm guessing that's not what you want.  If it is, ignore me.

You either need an absolute path to univ-xml[2], or you need to store it in a 
variable before the first for-each changes the context.  For example:

<xsl:variable name="univ-xml-2" select="univ-xml[2]"/>
<xsl:for-each select="document(univ-xml[1])/...">
  ...
  <xsl:for-each select="document($univ-xml-2)/...">
    ...
</>
