## XmlSchemaElement class


Represents the **element** element from XML [Schema](../) as specified by the World Wide [Web](../../system.web/) Consortium (W3C). This class is the base class for all particle types and is used to describe an element in an XML document.

```cpp
class XmlSchemaElement : public System::Xml::Schema::XmlSchemaParticle
```

## Methods

| Method | Description |
| --- | --- |
| [get_Block](./get_block/)() | Returns a **Block** derivation. |
| [get_BlockResolved](./get_blockresolved/)() | Returns the post-compilation interpretation of the **Block** value. |
| [get_Constraints](./get_constraints/)() | Returns the collection of constraints on the element. |
| [get_DefaultValue](./get_defaultvalue/)() | Returns the default value of the element if its content is a simple type or content of the element is **textOnly**. |
| [get_ElementSchemaType](./get_elementschematype/)() | Returns an [XmlSchemaType](../xmlschematype/) object representing the type of the element based on the [XmlSchemaElement::get_SchemaType](./get_schematype/) or [XmlSchemaElement::get_SchemaTypeName](./get_schematypename/) values of the element. |
| [get_ElementType](./get_elementtype/)() | Returns an object based on the [XmlSchemaElement](./) or [XmlSchemaElement](./) of the element, which holds the post-compilation interpretation of the **ElementType** value. |
| [get_Final](./get_final/)() | Returns the **Final** value to indicate that no further derivations are allowed. |
| [get_FinalResolved](./get_finalresolved/)() | Returns the post-compilation interpretation of the **Final** value. |
| [get_FixedValue](./get_fixedvalue/)() | Returns the fixed value. |
| [get_Form](./get_form/)() | Returns the form for the element. |
| [get_IsAbstract](./get_isabstract/)() | Returns information to indicate if the element can be used in an instance document. |
| [get_IsNillable](./get_isnillable/)() | Returns information that indicates if **xsi:nil** can occur in the instance data. Indicates if an explicit nil value can be assigned to the element. |
| [get_Name](./get_name/)() | Returns the name of the element. |
| [get_QualifiedName](./get_qualifiedname/)() | Returns the actual qualified name for the given element. |
| [get_RefName](./get_refname/)() | Returns the reference name of an element declared in this schema (or another schema indicated by the specified namespace). |
| [get_SchemaType](./get_schematype/)() | Returns the type of the element. This can either be a complex type or a simple type. |
| [get_SchemaTypeName](./get_schematypename/)() | Returns the name of a built-in data type defined in this schema or another schema indicated by the specified namespace. |
| [get_SubstitutionGroup](./get_substitutiongroup/)() | Returns the name of an element that is being substituted by this element. |
| [set_Block](./set_block/)(XmlSchemaDerivationMethod) | Sets a **Block** derivation. |
| [set_DefaultValue](./set_defaultvalue/)(const String\&) | Sets the default value of the element if its content is a simple type or content of the element is **textOnly**. |
| [set_Final](./set_final/)(XmlSchemaDerivationMethod) | Sets the **Final** value to indicate that no further derivations are allowed. |
| [set_FixedValue](./set_fixedvalue/)(const String\&) | Sets the fixed value. |
| [set_Form](./set_form/)(XmlSchemaForm) | Sets the form for the element. |
| [set_IsAbstract](./set_isabstract/)(bool) | Sets information to indicate if the element can be used in an instance document. |
| [set_IsNillable](./set_isnillable/)(bool) | Sets information that indicates if **xsi:nil** can occur in the instance data. Indicates if an explicit nil value can be assigned to the element. |
| [set_Name](./set_name/)(const String\&) | Sets the name of the element. |
| [set_RefName](./set_refname/)(const SharedPtr\<XmlQualifiedName\>\&) | Sets the reference name of an element declared in this schema (or another schema indicated by the specified namespace). |
| [set_SchemaType](./set_schematype/)(const SharedPtr\<XmlSchemaType\>\&) | Sets the type of the element. This can either be a complex type or a simple type. |
| [set_SchemaTypeName](./set_schematypename/)(const SharedPtr\<XmlQualifiedName\>\&) | Sets the name of a built-in data type defined in this schema or another schema indicated by the specified namespace. |
| [set_SubstitutionGroup](./set_substitutiongroup/)(const SharedPtr\<XmlQualifiedName\>\&) | Sets the name of an element that is being substituted by this element. |
| [XmlSchemaElement](./xmlschemaelement/)() | Initializes a new instance of the [XmlSchemaElement](./) class. |
## Typedefs

| Typedef | Description |
| --- | --- |
| [Ptr](./ptr/) | An alias for shared pointer to an instance of this class. |
## Remarks



Objects of this class should only be allocated using [System::MakeObject()](../../system/makeobject/) function. Never create instances of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../../system/smartptr/) pointer and use this pointer to pass it to functions as argument.
