Creating typed dataset from an industry standard schema

[Jeremy Summers]

Has anyone run into problems creating typed datasets from complex schemas?

I am attempting to create a Typed Dataset in Visual Studio .Net from a .xsd
schema file for a industry standard web service. I have run the schema
through XML Spy and validated it with no errors, but when attempting to
generate a dataset, I keeping getting a 'undefined data type' error. The
schema is quite large so I don't know if that is causing the problem or if
it is just something odd about .Net's parser. Here is the section of the
schema causing the problem. There are only two spots where the token type
is used in the schema, but I can't just pull them out because the there are
other types that are derived from this.

<xsd:simpleTy pe name="NC_NoID">
<xsd:restrictio n base="xsd:token ">
<xsd:minLengt h value="1" />
<xsd:pattern value="[\p{IsBasicLatin }]*" />
</xsd:restriction >
</xsd:simpleType>

Here are the tags from the top of the schema file:

<xsd:schema xmlns:xsd="http ://www.w3.org/2001/XMLSchema"
xmlns="http://www.ACORD.org/standards/PC_Surety/ACORD1.3.0/xml/"
