Aux info record - ERROR_STRING

This is a type of aux info record. This record pertains to the XEC_CTL_ERROR_HANDLING features. It has the following format:
Table 1. Aux info record - Error_String
  Fields
+0 record type flags reserved
+4 record length
+8 aux flag aux type = 0x0102
+C failing string length
+10 failing string value
The failing string contains a string in the form of a length/value pair from the document which is associated with the failure. The parser will test the failing byte sequence. If it is in an US-ASCII displayable range of characters, then the character itself will be present in the string. If it is not displayable, it will instead be the hex representation. These will follow the C convention of 0xnn. For example, if a character is found which is not allowed in an xml document, then it may show here as 0xC270.

In cases where the XEH_ERRREPTEXT bit is on in the error location record, this string will contain the entity reference in the main document which led to the error occurrence.
