[xsl] Escaping an apostrophe for JavaScript

["Frank T. O'Connor" <foconnor at kabel-us dot com>]

Using MSXML3.

Trying to write the following string:
  <img 
    src="blah.gif" 
    onMouseOver="window.status='Frank O\'Connor'; return true;"
  />

The problem is my source XML doesn't have the apostrophe escaped for
javascrpt. The source node simply has "O'Connor" in it.
I can't seem to figure out any way of using translate or substring to
convert the apostrophe to a backslash-apostrophe. There doesn't seem to
be any way to locate the location of a substring within a string. Unless
I loop it one character at a time.

I was thinking perhaps I could make up a entity that is
backslash-apostrophe, and then tell translate to replace apostrophe with
this entity.

But I'm not sure where to put this DTD information in my XSL file. 

I tried this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [
	<!ENTITY test "\&apos;">
]>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
...
</xsl:stylesheet>

but I get this error:
The element 'xsl:stylesheet' is used but not declared in the DTD/Schema


any suggestion?

Thanks,
