Replace the Annex A of ISO/IEC 9541-1:1991 with the following Annex:
This annex defines a typeface design grouping scheme whose purpose is to provide values for the mandatory DSNGROUP property defined in clause 8.6.15. This grouping scheme consists of a three-level hierarchical structure. The highest (most general) level of the hierarchy is the ISO Class, the second level of the hierarchy is the ISO Subclass, and the third (most specific) level of the hierarchy is the ISO Specific Group. Typeface examples for each Specific Group are shown and named wherever possible. These illustrations are intended to serve only as informative examples, not as a comprehensive catalog.
Typefaces which are similar in appearance or which have characteristics that would allow them to be reasonably substituted for each other, are grouped together.
Some type designs could be associated with more than one design group, but it is the responsibility of the type designer or font resource generator to choose the most appropriate group.
This typeface grouping scheme has the following intended purposes:
To aid both people and software applications in initial selection of typefaces, either in their system or on remove font servers, which closely resemble a specified style which is not available.
To provide information that will enable identification of fonts for different international scripts (such as Kanji and Latin) that will harmonize well when used on a page of a multi-script document (assuming the weights are matched). Assignment of suitable representations of different scripts to existing classes is encouraged to support this purpose.
To help software applications do font substitution, based on style characteristics, when a font referenced in a document is not available on a user's system. Font substitution based on style alone can cause a document to be reformatted since the metrics are likely to be different. However, this may be adequate for some applications. The classification information contained in this document can also be useful for systems capable of more advanced forms of substitution.
When using this grouping scheme, it may be necessary to consider properties additional to those described in clause 8 when selecting substitution fonts. Since the grouping value specifies only the style and appearance of a font, additional properties such as NOMCAPSTEMWIDTH, LCHEIGHT, and metrics can prove useful in matching the layout and typographic color of a page, and in achieving the best overall match.
NOTE 42 Throughout this grouping scheme, the term "serif" is used to denote both the traditional concept of the serifs of Roman typefaces, as well as any style of non-plain stroke-ending used in a non-Latin typeface. Although non-Latin typefaces with non-plain stem endings are included in groups with "serif" in their names, it may generally be improper to refer to them as "serif" typefaces. The term "sans serif" is used to denote a plain, unembellished stroke ending.
Typefaces in this class use as a source of their design the Uncial writing hands of Europe used from the 4th to the 10th Century.
These designs are characterized by having one set of alphabetic glyphs having a mixture of both upper and lowercase letter shapes consistent with the historical Uncial book hand.
Typefaces in this group have the characteristics of Uncial glyph images, but have plain stem endings.
Typefaces in this group have the characteristics of Uncial, and have the serifs that were typical of the historical forms.
The designs of this subclass are characterized primarily by having distinct and separate upper and lowercase letter shapes (a characteristic not found in historical examples).
Typefaces in this group have duplex Uncial forms with plain stem endings.
Typefaces in this group have duplex Uncial forms with serifs for stem endings.
Latin typefaces of this general class have the characteristics of being based on monumental lettering which was cut in stone. Generally they include only uppercase letters and are based on the proportions of the classic Roman inscriptional glyph images, e.g., having a narrow "E", "F", and "L".
These designs have solid stems.
Typefaces in this group are based on inscriptional styles, have solid stems, and plain stem endings.
Typefaces in this group are based on inscriptional styles, have solid stems, and non-plain stem endings.
These designs have a fine line in the stem which gives the appearance that the lettering is incised in stone or wood.
Inscriptional style typefaces with inlines and plain stem endings.
Inscriptional style typefaces with inlines and nonplain stem endings.
The designs of this subclass are characterized by single lines that define the contour or outline of the glyphs.
This group consists of outlined inscriptional styles with plain stem endings.
This group consists of outlined inscriptional styles with non-plain stem endings.
Designs in this class are characterized by relatively bold, angular, and condensed character shapes. Latin typefaces in this class are generally based on the late medieval European book hands known as the Blackletter style. Some variations include bold rounded styles as well as less formal designs showing cursive influences. Non-Latin typefaces in this class are those based on bold and angular designs.
The designs of this subclass are characterized by their condensed appearance; large x-height; with little or no curves, giving an angular look to the lowercase. Latin-alphabet versions of these typefaces were, historically, reserved for Bible printing, and were based on the ecclesiastical writing style.
This group consists of formal Blackletter designs with plain stem endings.
This group consists of formal Blackletter designs with serifs for stem endings.

The designs of this group have handwritten appearance with some decoration.
