Abstract: A system and method for constructing documents has files containing data and instructions. The data forms logical streams for provision to output means. According to the method, a plurality of referents referring to logical streams of data are provided. A plurality of different referent scopes with which referents are associated and used and outside of which referents within a scope are inaccessible are also provided. Referents are then inserted into the logical stream of data and within a referent scope from the plurality of referent scopes. The logical streams of data referred to by referents within a referent scope are then resolved but resolving of a referent scope does not necessarily result in a resolved logical stream of data absent referents. Once the referent scopes are resolved, the resulting logical data stream is provided to the output device as a constructed document. A system having parts for performing the steps of the method is also disclosed.
