XUpdate specifications

Hello all,

is there any reference on XUpdate dialect implemented in eXist? I mean list of available functions, restrictions etc.

I've been used snapshot eXist-snapshot-20040804.jar up to yesterday and such XUpdate was completed successfully:

 

<xupdate:modifications version="1.0"  xmlns:xupdate="http://www.xmldb.org/xupdate">
   <xupdate:append select="//class" >    
      <xupdate:attribute name="order">1</xupdate:attribute>      
   </xupdate:append>
</xupdate:modifications>

 

But with latest eXist-snapshot-20040922.jar it raises "Internal server error" which disappears on this query (class id specified):

 

<xupdate:modifications version="1.0"  xmlns:xupdate="http://www.xmldb.org/xupdate">
   <xupdate:append select="//class[@id='1']" >    
      <xupdate:attribute name="order">1</xupdate:attribute>      
   </xupdate:append>
</xupdate:modifications>

 

How I could stay in touch of XUpdate dialect changes?
