RE: Attributes from a different namespace

Thanks a lot Pete. Regarding your last observation, does that really
matters that I should use "xs" instead of "java".

May be I didn't understand what you were trying to say.

Thanks,
Swayam

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.

Prakash Bettadapur (private) -->

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

            </java:restriction>

      </java:simpleType>

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

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

Iam getting error in base1.xsd saying

Schemas
