Abstract
A portion data structure representing a portion extracted from a formatted source document is described. A portion data structure contains a first subtree of nodes that is modeled after a second subtree of a complete hierarchical representation of the formatted source document. Explicit formatting attribute values are specified for nodes of the first subtree only where a value calculated for the formatting attribute in a node of the first subtree differs from a value calculated for the formatting attribute in the corresponding node in the second subtree at a time when the node of the first subtree descends from a reset node specifying standardized formatting attribute values. The contents of the portion data structure are usable to display the portion extracted from the formatted source document in a context other than the formatted source document.
