ORA-600 [qmxtcCtxConvertString] when executing select dbms_xmlgen.convert('a & b', 1) from dual;
The top of the stack trace is:
qmxtcCtxConvertString <- spefcpfa <- spfmccallstd <- pextproc <- psdexsp
If a valid escape code is used for the ampersand then the query succeeds.
The problem is that updateXML() should accept text including non-escaped general entities, but due to this problem is does not. The error ORA-31067 'XML nodes must be updated with valid nodes and of the same type' may be reported as well or instead of this error.
