`xsd.Particle`¶

The xsd.Particle class represents a part of a content model. When an element is validated against a xsd.ComplexTypeDefinition, its sequence of child elements is checked against the content model of the xsd.ComplexTypeDefinition and the children are attributed to xsd.Particle objects of the content model. A xsd.Particle specifies a term - i.e. an xsd.ElementDeclaration, a xsd.ModelGroup or a Wildcard (xsd.Any) schema component - and its occurrence constraints.

class xsd.Particle¶: Proper instances of this class will be created within RaptorXML only, instantiation from script code will throw a NotImplementedError exception.

Attributes¶

xsd.Particle.annotations¶: Returns an iterator of xsd.Annotation components.

xsd.Component.element: Returns the xml.ElementInformationItem representing this schema component.

xsd.Component.id: Returns the value of the ‘id’ attribute as a string, or None if the schema component’s XML element doesn’t have an ‘id’ attribute.

xsd.Particle.max_occurs¶: Returns the upper bound of occurrence for the term of this xsd.Particle. This is either an integer value greater than 0 or the special Value “unbounded”. When the term is an xsd.ElementDeclaration or Wildcard (xsd.Any), the number of such element children must be less than or equal to any numeric specification of max_occurs; if max_occurs is “unbounded”, then there is no upper bound on the number of such children.

xsd.Particle.min_occurs¶: Returns the lower bound of occurrence for the term of this xsd.Particle. This is an integer value greater than or equal to 0. When the term is an xsd.ElementDeclaration or Wildcard (xsd.Any), min_occurs determines the minimum number of such element children that can occur. The number of such children must be greater than or equal to min_occurs. If min_occurs is 0, then occurrence of such children is optional.

xsd.Particle.term¶: Returns the term of the xsd.Particle, this is either an xsd.ElementDeclaration, xsd.ModelGroup or Wildcard (xsd.Any) schema component.
