Use of the slant and weight keywords to capture italicization and bold type

The slant keyword is used to designate whether the element is in italics or not. The value italic specifies italics; the value upright specifies roman type. These values are designed for use in early printed texts where degrees of obliquity are not at issue. If you need a more fine-grained vocabulary to describe the types in your documents, you can create additional keywords.

The weight keyword is used to designate whether the element is in bold face or not. Possible values are light, normal, and bold. The WWP does not currently use this keyword at all; boldface type is very rare in texts from our period (in fact it is not clear whether it appears at all). Sometimes differences of type size give a misleading impression; boldness should only be specified where a direct comparison can be made between the text in question and other non-bold text of the same size and font, to be certain that the appearance of added weight is not simply the result of a larger type size.
