Defining entity properties

122
Entities enable you to include predefined values, external XML or non-XML
files in an XML model targeted with a DTD.
When an XML processor reads an entity reference in an XML document, it
will replace this entity reference by its value defined in the DTD file of the
XML document.
An entity reference is the entity name preceded by an ampersand and
followed by a semicolon.
For example: &glossary; will be replaced by See Glossary.
The W3C has predefined five entities for XML tags:
Entity name
Less than
Greater than
Ampersand
Apostrophe
Quotation
In an XML model, you just need to type the name and the value of an entity.
To display an entity property sheet, double-click its name or its icon in the
Browser tree view.
The General page of an entity property sheet displays the following
properties:
Property Description
Name Name of the entity. It must be a no-colon-name (See Glossary)
Code Code of the entity. It must be a no-colon-name
Comment Descriptive label of the entity
Stereotype Sub-classification used to extend the semantics of an object
without changing its structure. It can be predefined or user-
defined
