It was puzzling me too. I use Oxygen's Eclipse plugin for testing the 
XSLT. Normally it simply lists all the errors. Now it just said 
"Transformation failed". I learned something: try it outside of the IDE 
box. The following happens:
With this stylesheet:
---------------------
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="2.0">
   <xsl:template match="/">
       1) <xsl:value-of select="document-uri(document(''))"></xsl:value-of>
       2) <xsl:value-of select="static-base-uri()"></xsl:value-of>
       3) <xsl:value-of select="base-uri(.)"></xsl:value-of>
   </xsl:template>
</xsl:stylesheet>

This output:
------------
<?xml version="1.0" encoding="UTF-8"?>
       1) file:/D:/Workspaces/Eclipse/etc/def/config/test.xslt
       2) file:/D:/Workspaces/Eclipse/ect/def/config/test.xslt
       3) file:/D:/Workspaces/Eclipse/etc/def/config/test.xml


With this stylesheet:
---------------------
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
   version="2.0" xml:base="../..">
   <xsl:template match="/">
       1) <xsl:value-of select="document-uri(document(''))"></xsl:value-of>
       2) <xsl:value-of select="static-base-uri()"></xsl:value-of>
       3) <xsl:value-of select="base-uri(.)"></xsl:value-of>
   </xsl:template>
</xsl:stylesheet>

This output:
------------
Error on line 1 column 1 of file:/D:/Workspaces/Eclipse/etc/:
 SXXP0003: Error reported by XML parser: Content is not allowed in prolog.
Recoverable error on line 5 of 
file:/D:/Workspaces/Eclipse/etc/def/config/test.xslt:
 FODC0005: org.xml.sax.SAXParseException: Content is not allowed in prolog.
<?xml version="1.0" encoding="UTF-8"?>
       1)
       2) file:/D:/Workspaces/Eclipse/etc/
       3) file:/D:/Workspaces/Eclipse/etc/test.xml



I believe in the light of what all people said on this subject, this 
behavior is to be expected.

The xml:base was used to make xsl:import easier. I did not want to add 
it to each xsl:import statement. But I guess, I'd have to decide on the 
pros and cons of either technique. At least I understand now what's 
happening.
