Change Notes for Implementors

Parameter Entities for Attributes

In previous versions of this Tag Set, some parameter entities for groups of attributes were used to make other parameter entities and occasionally two or more elements shared a parameter entity. In version NISO 0.4 (NLM 3.1), such dependencies have been reduced, and each element has a parameter entity for its attributes, ending in “ -atts ”. The new parameter entities implement the same attribute lists, so no XML document will be made invalid. However, if a Tag Set has been customized, those customizations should be examined in the light of the new parameter entities. Some customizations may need to change to use the new Parameter entities and some implementors may wish to change for the3 sake of increased compatibility with the base Tag Set and increased flexibility.

The following changes have been made to attribute list parameter entities:

Style for Textual Form Parameter Entities

Textual Form Elements Parameter Entity. Corrected an error that had the parameter entity %textual-form-elements; started with an element instead of an OR bar, as inline mixes (elements groupings) should be. The parameter entity now begins with an OR bar and the OR bar has been removed from the model of <textual-form>. Customizations should be updated to match.
