RecordSize (4 bytes): A 32-bit unsigned integer that defines the number of WORD structures, defined in [MS-DTYP] section 2.2.61, in the record.
RecordFunction (2 bytes): A 16-bit unsigned integer that defines this record type. The lower byte MUST match the lower byte of the RecordType Enumeration (section 2.1.1.1) table value META_ESCAPE.
EscapeFunction (2 bytes): A 16-bit unsigned integer that defines the escape function. The value MUST be 0x0008 (QUERYESCSUPPORT) from the MetafileEscapes Enumeration (section 2.1.1.17).
ByteCount (2 bytes): A 16-bit unsigned integer that specifies the size, in bytes, of the Query field. This MUST be 0x0002.
Query (2 bytes): A 16-bit unsigned integer that MUST be a value from the MetafileEscapes Enumeraton. This record specifies a query of whether this escape is supported.
See section 2.3.6 for the specification of other Escape Record Types.
