Proposed name of the entity, according to the domain name structure as defined in clause 4: Example: Entity category . . . . extended attribute Proposed name of entity . . fontsize Short description
29、 of the submitted entity (e.g. main purpose or intended effect.) Example: Specification of character size for text contents. Syntactic specification of submitted entity, according to the entity category Contained elements (e.g. values, parameter, content data): For any component or element contained
30、 in the entity, this shall specify all characteristics necessary for unambiguous interpretation (at least: name, type, valid data values, defaults). Identification of updatable information (what is open to later changes): Error conditions and proposed handling: Example: Contained elements: fontsize,
31、 INTEGER, 0255, 0 Updatable information: valid data range (could possibly be increased) Error handling: values outside of valid range: ignore set for objects other than content objects containing/referencing text data: ignore Full description of semantics and behaviour of the submitted entity (natur
32、al language) (e.g. how to be interpreted, possible side effects, work arounds if it cannot be supported.) Example: The attribute fontsize, which can be set and retrieved by the elementary actions: - SetCataloguedAttribute - GetCataloguedAttribute, respectively, allows for controlling the presentatio
33、n of textual content with respect to character size. The units in which its value is to be interpreted are points. The value 0 means that it is up to the MHEG engine (or presentation tools) which fontsize is to be used for rendering the text content. Note that this is also the default behaviour as l
34、ong as this attribute is not set explicitly. If the requested fontsize cannot be supported, it shall be replaced by the closest available one. If the application of the requested fontsize value results in a rendering of the associated text content, which does not fit into the Original Presentation S
35、pace (OPS) of the n-content object, it shall be rendered into the OPS in the usual way until available space is exhausted; in other words, clipping shall be applied to trailing parts of the text. Constraints for application (e.g. under which conditions to be applied or ignored.) Example: This attrib
36、ute shall be applied only to rt- content objects containing/referencing textual data. Otherwise, it should be ignored.
