XML Schema - conditionally include attributes

["Morcom, Harvey" <Harvey.Morcom@KPMG.co.uk>]

Is it possible to have an attribute appear on an element based on the value of another attribute. For example,

<Emphasis style="bold">Bold text</Emphasis> 

However if the value of the style attribute is 'background-color' I would then like a color attribute to appear;

<Emphasis style="background-color" color="silver">Bold text</Emphasis>

Thanks in advance
