My solution would go like this:
At the top of the stylesheet, use the document function to write the 
exclude-attr elements into a variable (so that I only have to use the 
document function once).
In the modify-attr template, see if the current node has a matching 
exclude-attr element (by examining the contents of that variable).
If not, write the modify-attr element to the result.

So, I'd end up with this:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
  <xsl:variable name="exclude" select="document('excludedoc.xml')"/>

  <xsl:template match="modify-attr">
    <xsl:variable name="name" select="@attr-name"/>
    <xsl:if test="not($exclude/exclude-list/exclude-attr[.=$name])">
      <xsl:copy-of select="."/>

Tested with Saxon 8.4 and Xalan-J 2.4.1.

[xsl] xsl:for-each...iteration question

This has been answered before I'm sure but doing a relevant search in the 
archives is tricky.
I've an input doc containing a number of modify-attr elements
  <modify-attr attr-name = "abc"/> 
  <modify-attr attr-name = "123"/>
  <modify-attr attr-name = "789"/>
I have another document containing a list of prohibited attributes.
I want to iterate over my input doc and copy all those modify-attr 
elements that are NOT in the exclude list to the output.
<xsl:template match="modify/modify-attr">
  <xsl:variable name="currentAttr" select="@attr-name"/>
  <xsl:variable name="currentNode" select="."/>
  <xsl:for-each select="document('excludedoc')/exclude-list/exclude-attr">
    <xsl:when test="$currentAttr=.">
      <xsl:copy-of select="$currentNode"/>
Obvisouly, this is flawed, I get multiple modify-attr elements copied to 
the output because I cannot see a way of ensuring the for-each only copies 
a permitted node once and once only.
I've a feeling this is approaching the problem from the wrong way....
