## Conformance

Abstract

xmlroff Conformance to XSL 1.0 Recommendation

The XSL Recommendation defines the behaviors of two classes of formatters based on their media type: visual and aural. It further divides the class of visual formatters into interactive media and non-interactive media formatters.

xmlroff is a visual formatter for non-interactive media.

xmlroff implements a range of formatting objects and properties from the Basic, Extended, and Complete conformance levels.

xmlroff does not claim Basic conformance to the XSL Recommendation since it does not yet implement all of the Basic level formatting objects and properties.

xmlroff supports both "lr-tb" and "rl-tb" values of the writing-mode property (and the "lr" and "rl" shorthands).

### Conformance Levels

From Section 8, Conformance, of the XSL Recommendation:

> This specification defines three levels of conformance, in order of completeness:

> Level | Description
> --- | ---
> Basic | Includes the set of formatting objects and properties needed to support a minimum level of pagination or aural rendering.
> Extended | Includes everything else, except for shorthands. It is intended for applications whose goal is to provide sophisticated pagination.
> Complete | Includes everything.

> Conformance to this specification is expressed in terms of conformance to any of the above levels.

> An application that claims conformance to a given level of this specification must implement all the formatting objects and properties that apply to it for a given medium.

Conformance for visual and aural XSL formatters is defined separately for each formatting object. For example, implementing fo:page-number is necessary for Basic level conformance for a visual formatter, but only necessary for Extended level conformance for an aural formatter.

In contrast, formatting object properties only have one defined conformance level, but there are also some properties that apply to only one class of formatter. For example, page-height and voice-family are both in the set of properties for Basic level conformance, but page-height applies only to visual media and voice-family applies only to aural media.

Appendix B and Section C.3 of the XSL Recommendation list a proposed fallback treatment for each Extended level formatting object and property. The fallbacks are defined "[i]n order to ensure interoperability." Also, "[c]orrect processing of fallbacks does not constitute conformance."

All formatting objects are assigned to either Basic or Extended level conformance. There are no Complete level formatting objects.

Some formatting objects are specific to Extended level conformant interactive media formatters. Non-interactive media formatters such as xmlroff, however, must, for Extended level conformance, implement the proposed fallback treatment of the Extended level interactive media formatting objects.

### Stated Conformance

The stated conformance also has three levels:

Level | Description
--- | ---
Yes | xmlroff implements the formatting object, property, or fallback behaviour, possibly with some caveats.
No | xmlroff does not implement the formatting object, property, or fallback behaviour, but a workaround may also be suggested.
N/A | xmlroff does not need to formatting object, property, or fallback behaviour. For example, xmlroff does not implement properties for aural or interactive presentation, and it does not implement fallback behaviour for implemented formatting objects.

### Formatting Objects

All the formatting object specified by the XSL 1.0 Recommendation are accepted. Not all are supported, however.

The following tables are based on the tables in Appendix B of the XSL Recommendation. The conformance level and proposed fallback treatment for visual processors are shown along with an indication of whether xmlroff implements the formatting object or the fallback treatment. Conformance level and fallbacks for aural processors are not shown.
