Difference between xs:simpleType & xs:complexType

[selvam]

Hi,

Can anyone help me in explaining the difference between the xs:simpleType & xs:complexType?

I am bit confused with these two.

Please explain these two with the proper example.

When should we go for simpleType and when should we  go for xs:complexType?

Also explain about simplexContent and complexContent?

Thanks
Selvam

Complex types allow element children, simple types don't.

So <a><b/></a> has a complex type, while <a>ddd</a> has a simple type.

"Complex types with simple content" allow attributes but not child elements,
for example

<a b="1">ddd</a>

A complex type with "Mixed content" allows character data as well as child
elements, for example

<p>Some <i>italic</i> text</p>

The only time there's any confusion is with empty elements <a/>, which can
be modelled as either complex or simple depending on your whim.

Hi Selvam,

You may find the following introduction to schema useful:

I believe if you want an element to have an attribute, that element
must be a complexType.

[selvam]

thanks..

you mean "Mixed Content" as "complexContent" right?

Can you also explain me the way how the xs:any and xs:anyAttribute will work?
what is the diff b/w namespace="##any", "##other", "##local", "##targetNamespace"?

So  has a complex type, while ddd has a simple type.

"Complex types with simple content" allow attributes but not child elements,
for example

ddd

A complex type with "Mixed content" allows character data as well as child
elements, for example

<p>Some italic text</p>

The only time there's any confusion is with empty elements , which can
be modelled as either complex or simple depending on your whim.
