I did consider a Schema definition for BSWML to ensure valid data, but it appears that Schema can not validate hexadecimal ranges and can not validate against more than one range (required for <seq> tag).

A <sym> as 2 mandatory attributes "x" and "y"; each with a valid range of -1919 to 1918.  The <sym> value is hexadecimal with a value range of 0100 to EBBF.   The <sign> tag can also have zero or more <seq> tags with a hexadecimal value in the range of 0100 to EBBF or in the range of EDA0 to F09F.
