You can preserve the formatting for detailed tagging in the instance document. Formatting options are associated with nonnumeric XBRL mappings in which the string is based on concepts of the “xbrl.us:TextBlockItemType” type and its derivatives. The available formatting options include:
Rich text—Disclosure Management extracts the HTML formatted content from Office document and applies this formatting to the nonnumeric item.
Plain text—Disclosure Management uses the formatting value of the corresponding fact and applies the formatting to the nonnumeric item.
Default—A plain text format is applied to nonnumeric items by default. However the default configuration can be set to use the rich text format for certain string types and their derivatives.
