If you wanted to keep your attribute named as IsHidden, then in your first 
schema you could do:

 <java:simpleType name="IsBridge">
    <java:restriction base="java:boolean"/>
 </java:simpleType>

which effectively sets up an alias for the boolean type, and then in your 
second schema so:

 <xs:attribute name="IsHidden" type="java:IsBridge"/>

If you still wanted an attribute called IsBridge in your first schema, you 
could include in it:

    <java:attribute name="IsBridge" type="IsBridge"/>

(The two names are in different namespaces.)

(BTW - In your first schema I would also make the prefix associated with the 
http://www.w3.org/2001/XMLSchema namespace be 'xs' as you have done in the 
second schema.)

HTH,

Pete.

Thanks Michael.

Well my intention was to use the IsBridge attribute in java1.xsd in
base1.xsd. That's all.

After some trial and error I solved my problem by using below in my
base1.xsd, it worked



<xs:attribute ref="java:IsBridge"/>



Pl let me know if there is any better way of doing the same.



Thanks

Swayam

You can't write type="java:IsBridge" because java:IsBridge is an
attribute, not a type.



I'm not sure what you wanted it to mean.

Hi All,



Iam newbie regarding xml and xsd. I am facing below issue, Can
anyone please tell me a way out.



I have below schema - java1.xsd



<?xml version="1.0" encoding="UTF-8"?>

<!-- edited with XMLSpy v2005 rel. 3 U (http://www.altova.com) by
Prakash Bettadapur (private) -->

<java:schema xmlns="http://www.cisco.com/efg/abc/java"

xmlns:java="http://www.w3.org/2001/XMLSchema"

attributeFormDefault="unqualified" elementFormDefault="qualified"

targetNamespace="http://www.cisco.com/efg/abc/java">

      <java:simpleType name="javaTypeOfReference">

            <java:restriction base="java:string">

                  <java:enumeration value="Set"/>

                  <java:enumeration value="Bag"/>

                  <java:enumeration value="List"/>

            </java:restriction>

      </java:simpleType>

      <java:attribute name="IsBridge" type="java:boolean"/>

</java:schema>





I have imported above xsd into below schema - base1.xsd, a
snippet of which is as shown below

Error

            <xs:anyAttribute namespace="##other" processContents="lax"/>

      </xs:complexType>

Iam getting error in base1.xsd saying

Problems were detected while validating and converting the XML
Schemas
