Generating Restrictions in XML Schema Dynamically Using VB.NET 2005: Preliminaries - Differences between xxxExclusive and xxxInclusive
(Page 5 of 5 )
This has caused a lot of confusion among several beginners when they design a new XML Schema. Let us consider the following fragment of XML Schema:
<xs:element name="age">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:minExclusive value="1" />
<xs:maxExclusive value="100" />
</xs:restriction>
</xs:simpleType>
</xs:element>
According to the above code fragment, both values are “exclusive” during validation. That means the “Age” element can have data between 2 and 99 (both inclusive) only. Let us consider the following code fragment:
<xs:element name="age">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:minInclusive value="1" />
<xs:maxInclusive value="100" />
</xs:restriction>
</xs:simpleType>
</xs:element>
According to the above code fragment, both values are “inclusive” during validation. That means the “Age” element can have data between 1 and 100 (both inclusive) only. We can also mix them according to our necessity. Let us consider the following code fragment:
<xs:element name="age">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:minExclusive value="1" />
<xs:maxInclusive value="100" />
</xs:restriction>
</xs:simpleType>
</xs:element>
According to the above code fragment, the “Age” element can have data between 2 and 100 (both inclusive) only. Let us consider the following code fragment:
<xs:element name="age">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:minInclusive value="1" />
<xs:maxExclusive value="100" />
</xs:restriction>
</xs:simpleType>
</xs:element>
According to the above code fragment, the “Age” element can have data between 1 and 99 (both inclusive) only.
I hope the above examples clear up any confusion among the usage of “Inclusive” and “Exclusive” facets available when making restrictions in XML Schema.
