Cannot display complete document in binary XML XMLType column

Question

I've been trying to get a query to work that will display the complete XML document stored in a column of XMLType, binary XML storage.
<b/>
I"m using Toad 10.6.1.3.
<b/>
I'm running Oracle client:
{code}Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production
CORE 11.1.0.7.0 Production
TNS for Linux: Version 11.1.0.7.0 - Production
NLSRTL Version 11.1.0.7.0 - Production{code}
<b/>
The table is defined:
{code}CREATE TABLE AUDITED_EVENT_XML_MIN (
AUDITED_EVENT_XML_PK_ID NUMBER(10) PRIMARY KEY,
/* The time the audit record was created. */
CREATED_TIME TIMESTAMP(6) WITH LOCAL TIME ZONE NOT NULL,
/* Well-formed XML message */
XML_EVENT_CONTENT XMLType
XMLTYPE COLUMN "XML_EVENT_CONTENT" STORE AS BINARY XML;
{code}
<b/>
The XML has no namespace. The SQL that I tried is:
{code}select e.xml_event_content.extract('/') from AUDITED_EVENT_XML e;{code}
<b/>
I also tried a simpler approach.
{code}select * from AUDITED_EVENT_XML e;{code}
<b/>
and got this error:
{code}ORA-21500: internal error code, arguments: [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s]{code}
<b/>
I'm a newbie; I'm sure there is a simple way to do this; but I can't find it in the Oracle XML DB Developers Guide.
It would also be helpful to know how to do this for documents that have a declared namespace (without a xsd schema)...
Thanks in advance...

When ran from the Command window in PL/SQL Developer
Connected to Oracle Database 11g Enterprise Edition Release 11.1.0.6.0
SQL>
SQL> CREATE TABLE AUDITED_EVENT_XML_MIN (
  2      AUDITED_EVENT_XML_PK_ID NUMBER(10) PRIMARY KEY,

  6      XML_EVENT_CONTENT XMLType

  8      XMLTYPE COLUMN "XML_EVENT_CONTENT" STORE AS BINARY XML;

E.XML_EVENT_CONTENT.EXTRACT('/

</root>

I'm guessing your version of Toad (or something between it and the DB) does not like XMLType data types being returned.
Try
select e.xml_event_content.extract('/').getStringVal() from AUDITED_EVENT_XML_MIN e;or .getClobVal() if the XML is large and see what happens.
