Defining attribute group properties
Attribute group general properties
To display an attribute group property sheet,
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
