Validating a xml doc against schema

i'm confused about validation of xml doc against its schema. suppose i've the followings:
XML file ("note.xml"):
<?xml version="1.0"?>
xmlns="" xmlns:xsi=""
<body>Don't forget me this weekend!</body>
And the schema ("note.xsd"):
<?xml version="1.0" encoding="ISO-8859-1"?>
<xs:schema xmlns:xs=""
<xs:element name="note">
<xs:element name="to" type="xs:string"/>
<xs:element name="from" type="xs:string"/>
<xs:element name="heading" type="xs:string"/>
<xs:element name="body" type="xs:string"/>
if you look at the "note.xml" file where i've put an element "phone" which is not defined in schema "note.xsd". so when i validate from IE5 by right clicking on it and selecting Validate XML, no erorr is reported. i don't understand why. or is it because my validation process is wrong? my understanding is that a xml doc must not contain an element that's not defined in schema. please clarify me it. thanks.

I think for the xsi:schemaLocation you need to give the targetnamespace followed by the schema file name. I guess you missed giving the target namespace here. Try doing it that way.

IE5 doesn't validate your XML file. I don't think it even looks at the schema file at all.
In case of a DTD file, IE5 needs to retrieve entity values and default/constant values of attributes from the file. Therefore, IE5 checks the DTD syntax and reports DTD syntax errors.
