Chapter 3 Building an XML model

Defining a group of attributes

An attribute group is a set of attributes. You define an attribute group globally (with the Model menu) and then you reuse it locally (with only its reference) in the definition of an element, a complex type or another attribute group.

For example:

The quality attribute group is composed of the guarantee and qualityStandards attributes. The productA element reuses the quality attribute group via the Attributes page of its property sheet (See attribute group tools).

• Generated XSD file:
  
  
  In a schema, a group of attributes is declared with the <attributeGroup> tag. It can contain the following tags: <attribute>, <attributeGroup> or <anyAttribute>.
• Generated DTD file:
  

Attribute groups are not supported by XDR.
