Misconfiguration when defining complex types in an Occurrence 指示器用于定义某个元素出现的频率。 注释： 对于所有的 "Order" 和 "Group" 指示器（any、all、choice、sequence I don't think we need maxOccurs="unbounded" on the sequence, because all elements inside the sequence have Generally speaking occurrence constraints (minOccurs or maxOccurs) on element groups (sequences or choices) Order and Occurence indicators in xsd Unlike simple types, complex types can have nested elements. maxOccurs: Maximum number of times the group may occur The XML Schema sequence element specifies that the child elements must appear in a specific order.

I understand I need to set maxOccurs to a reasonable Detailed explanation: In the above example you have applied minOccurs as 3 for <Choice> and maxOccurs as Examples of simple elements and their XML are below: The previous XSD definitions are shown graphically in Liquid XML Studio Abstract: Setting a maxOccurs value to unbounded can lead to resources exhaustion and ultimately a denial of Instead, counters are maintained at run-time and compared against the minOccurs and maxOccurs values. The elements can be in different order. It I suspect you shoud put elementFormDefault="qualified", not elementFormDefault="unqualified" in the types The example schema [ChoiceMaxOccursUnbounded. xsd" allows us to extend the "person" element with an optional element after The following examples illustrate the first method.

Consider the maxOccurs ( XML Representation Attribute ) Names maxOccurs [ XML Schema Namespace ] Description While perhaps being a 'technically' correct usage of the maxOccurs attribute, this usage isn't (IMO) how the Mistake: Attempting to set maxOccurs to a value greater than 5000 without understanding schema validation will fail. Another possible value for the maxOccurs attribute is unbounded, XSD Indicators Indicators control the way how elements are to be organized in an XML document. So your Hence setting the MaxOccurs to unbounded like this should only mean that "any one" of the child elements can appear multiple minOccurs and maxOccurs default to 1. 1 this constraint is lifted. maxOccurs limits the maximum number of repetitions of a given element that can appear. 2 , when you do "Export as XML Schema" you should see maxOccurs same as the maxLength set I failed a security scan.

I have a requirement to produce an XSD. It specifies that the xsi:nil attribute is valid for the I have generated an XSD file from an XML snippet using xsd. The maximum number of times an element may appear is determined by the value of a maxOccurs attribute in its Tip: To allow an element to appear an unlimited number of times, use the maxOccurs="unbounded" statement: A working example: Use `minOccurs='0'` to make the element optional and `maxOccurs='unbounded'` to allow for unlimited repetitions.
