Sybase XML manual Defining attributes, XDR files

	Chapter 2 Building an XML model
Property	Description
Reference	Name of an attribute in the current model or another model
	opened in the workspace. A reference allows you to reuse an
	attribute with all its properties without having to define it
	again. Use the dropdown listbox to select an attribute in the
	current model. Use the Browse tool to select an attribute from
	any model opened in the workspace. If you select an attribute
	from another model, a shortcut is created with the referencing
	attribute. When you define a reference, name and code
	properties are grayed. The name and code are those of the
	target attribute
Type	Attribute data type. It must be a qualified name (See
	Glossary). Use the dropdown listbox to select a built-in data
	type. Use the Browse tool to select a simple type defined in
	the current model or another model opened in the workspace
Embedded Type	If selected, the attribute data type disappears and a <simple
	type> tag is created in the schema within the <attribute> tag.
	Only available in a model targeted with XSD
Derivation	Derivation method for the attribute data type. Used to extend
	or restrict the values of the attribute data type. When you
	define a derivation, the data type disappears. You must click
	Apply and then the Properties tool to select a type, a base
	type or member types for the corresponding derivation (list,
	restriction or union). Only available in a model targeted with
	XSD

Defining attributes	In a model targeted with the XML-Data Reduced language, attributes tags are
in XDR files	defined by different attributes:
