Prefix 's10' cannot be mapped to namespace name reserved for "xml" or "xmlns"

Question

I have been given a third party set of schemas which I have copied into my BizTalk Schemas project (I copied the top level folder containing the schemas into a folder I created in the BizTalk Schemas project). The set of schemas are stored in a series
of folders and each schema has one or more imports statement so the structure of the schemas in the folder must be maintained. I cannot change this structure as it is from a third party.
I get the above error when I try and test a map that uses one of the schemas. The issue is with the
http://www.w3.org/XML/1998/namespace. When I load the set of schemas in Visual Studio creates a number of 'reference targetNamespace' entry's and it is one of these with the above reserved namespace that is
causing the problem during XSLT compilation. When I debug the map it shows the prefix s10 assigned to the reserved namespace above which is causing the problem.
If I look at the raw XSD schema the 'reference targetNamespace' entry's are not present so I can only assume they get added when I copy the set of schemas into the BizTalk Schemas project.
Has anyone come across this issue or suggest a way around this as at the moment it is a blocker for me, thanks.

The simple answer to this problem is to go to the schema with the issue, and add the appropriate definition to the top of the schema element.
I recently had a similar issue and didn't like the whole transform/pipeline approach and figured it had to be simpler than that.
<xs:schema elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xml="http://www.w3.org/XML/1998/namespace"> 
<xs:import schemaLocation="xml.xsd"
namespace="http://www.w3.org/XML/1998/namespace" />
