Symptoms
When an empty string is passed to the XSLT Document() function it should parse the current stylesheet and return a single node, the root node of the stylesheet itself as stated in the W3C Standard (http://www.w3.org/TR/xslt#document). So when running a transformer in the database using the following XSL with document(''):
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:copy-of select="document('')"/>
</xsl:template>
</xsl:stylesheet>
The stylesheet should be returned. Instead we see either <doc/> or <doc><doc/>
Note the W3C Standard states:
Function: node-set document(object, node-set?)
...
Note that a zero-length URI reference is a reference to the
document relative to which the URI reference is being resolved;
thus document("") refers to the root node of the stylesheet; the tree
representation of the stylesheet is exactly the same as if the XML
document containing the stylesheet was the initial source document.
