This document discusses various types of restrictions that can be used in XSD schemas to define acceptable values for XML elements and attributes. It describes restrictions on values, sets of values, series of values, whitespace characters, and length. Examples are provided for restricting an element to a range of integer values and restricting an element to a set of enumerated values. Other schema concepts discussed include extension, list, union, sequence, and schema validation options.

1. XSD schema properties
BizTalk schema

2. XSD Restrictions
What is the meaning of Restrictions ?
Restrictions are used to define acceptable values for XML elements or
attributes

3. What type of restriction
• Restrictions on Values
• Restrictions on a Set of Values
• Restrictions on a Series of Values
• Other Restrictions on a Series of Values
• Restrictions on Whitespace Characters
• Restrictions on Length

4. Restrictions on Values
Ex: restriction of values such as you have an element represent age
Age should between 15 and 60 so you want to make restriction on age
Steps :
1. Create BizTalk project
2. Add schema with restriction values
3. Right click and add element with name age
4. Right click on element and choose properties
5. Convert base datatype to integer
6. Make derived by restriction

5. • Make max fact type to inclusive or exclusive depend on your business
• Determine the value minimum facet value and maximum facet value

9. Restrictions on a Set of Values
• To limit the content of an XML element to a set of acceptable values,
we would use the enumeration constraint
• Like the steps in previous example but there are option call
enumeration
• Click on enumeration and add the value you want every value in
separate record

11. Restrictions on Length
• To limit the length of a value in an element, we would use the length,
max Length, and min Length constraints.

13. Restrictions on a Series of Values
• o limit the content of an XML element to define a series of numbers
or letters that can be used, we would use the pattern constraint.
• The example below defines an element called "letter" with a
restriction. The only acceptable value is ONE of the LOWERCASE
letters from a to z

15. extension
• The extension element extends an existing simple Type or complex
Type element.
Attribute Description
id Optional. Specifies a unique ID for the element
base Required. Specifies the name of a built-in data type, a simpleType element, or a
complexType element
any attributes Optional. Specifies any other attributes with non-schema namespace

17. List And union property
• List allow Defines a simple type that contains a white space-separated
list of values of an inherited simple type.
• Union allow Defines a simple type that contains a union of the values
of two or more inherited simple types.

19. Sequence
• enquires the elements in the group to appear in the specified sequence
within the containing element.
Max Occurs
The maximum number of times the sequence can occur. The value can be an
integer greater than or equal to zero. To set no limit on the maximum
number, use the string "unbounded“
minOccurs
The minimum number of times the sequence can occur. The value can be an
integer greater than or equal to zero. To specify that this sequence group is
optional, set this attribute to zero.

21. Schema validation
• Right click on schema and select one of three
• Validate scheme
• Validate instance
• Generate instance
