configured error codes have no effect

[lueck]

The configurable error codes in xsl/errors.xsl do not have an effect. It is still XTMM9000 from <xsl:message> or XTMM9001 from <xsl:assert>.

Example

$ target/bin/xslt.sh -config:saxon.he.xml -xsl:xsl/document.xsl -s:test/matt.xml -ea ref=Matt:6
ERROR: member 'Matt:6' not found
Error at xsl:value-of on line 219 column 42 of document.xsl:
