New attributes in element

Hi all,

I am new here.

Could I add a new attribute to xsd:element without violating the schema?
For example, instead of,
	<xsd:element name = "name" type = "xsd:string"/>
I want
	<xsd:element name = "name" type = "xsd:string" display =
"Name"/>
                                                     ^^^^^^^
Notice "display" is not a standard attribute of xsd:element.

Thanks,

-Wenjie
