Chapter 2 Building an XML model
XSM User's Guide 83
♦ 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.
Defining attribute group properties
To display an attribute group property sheet, double-click its name or its icon
in the Browser tree view.
There are global and referencing attribute groups:
♦ Global attribute groups are defined with the Model menu. In a schema,
they are directly linked to the <schema> tag (root element). They can be
reused for any element, complex type or attribute group in the model
through references (See quality attribute group in the generated schema)
♦ Referencing attribute groups are used within an element, a complex type
or an attribute group definition. For this, you must use the attribute group
tools in the Attributes page of an element, a complex type or an attribute
group property sheet
