Maximum number of bytes to read into memory from the start of an XML document to perform the XQL queries that are defined in an XML document type. The XQL queries can be identifying queries or queries to extract attributes. In your document types, if you have XQL queries that point to nodes beyond the number of bytes you specify, the queries will fail.

Specify a positive integer greater than 1000. If you specify an integer less than 1000, Trading Networks reads 1000 bytes. If you do not specify this property, Trading Networks uses tn.BigDocThreshold.
