Can I fake a namespace reference in XSLT

Question

I have a xsl that i've copied out of Sharepoint, and pulled into visual studio.

Visual studio will not compile or apply the transfromation because of this error

XslTransformException
---------------------
Cannot find the script or external object that implements prefix 'http://schemas.microsoft.com/WebParts/v2/DataView/runtime'.

Can I tell VS to ignore the prefix? Or somehow provide a dummy schema to get the XSLT to work?

I was think of just removing all the references, editing my transform and then maybe put them back if I need them.
