Defining the attributes of an element | Sybase XML specs

Defining elements

Tool	Action	Result
	If you click an element symbol
	with the Complex Type tool, a
	complex type symbol appears
	superposed, but not linked, to the	No link
	element symbol. A global
	complex type cannot be the child
	of an element

If you click an element symbol with the Sequence tool, a sequence group particle appears linked to the element symbol

If you click an element symbol with the Choice tool, a choice group particle appears linked to the element symbol

If you click an element symbol with the All tool, an all group particle appears linked to the element symbol

Pointer indications

When you cannot click a symbol or an empty space in a diagram, the Pointer displays a forbidden sign (See complex type in Tool column). When there is a possibility to create a symbol above, below or next to another one, the Pointer displays an arrow indicating the corresponding direction (See elements in Tool column).

Defining the attributes of an element

Attributes are used to give additional information about elements.
