ABSTRACT:
A method is disclosed for defining the structure of a document by specifying the relationships between document elements in a data stream. A plurality of tabular specifications are provided, each of which includes a number of document elements. The logical relationship between each document element and all other document elements within each tabular specification is specified once for the entire tabular specification. The semantic interpretation for each tabular specification is associated with a named reference to that tabular specification so that multiple references to that tabular specification may yield different semantic interpretations. In this manner, it is possible to minimize the amount of specification to define a document by utilizing individual tabular specifications repeatedly. Additionally, a reference to a tabular specification may be utilized to modify the existing logical relationship between the document elements contained therein. In a preferred embodiment of the present invention, a range of allowable values for individual document elements within a tabular specification may be specified by the user.
