The second issue is https://issues.apache.org/jira/browse/XERCESC-1937
that was recently fixed; the workaround is to place the xsi:type *after*
the xsi:schemaLocation attribute.
For the first one, it is probably a bug: the specs define xsi:type as a
QName, and QName have a whitespace property of "collapse" that should
convert tabs and line feeds into spaces before trimming. Can you create
a JIRA issue for this one?
Thanks,
Alberto

Hi,
I noticed that Xerces-C 3.1.1 does not validate things that Altova XMLSpy 2011
and the XML Parser of the .NET Framework 2.0 do validate. Reading the W3C
standards, I fear that Xerces-C is not fully standards conform, but I want to
have some others have a look at it before I file a JIRA issue.
First issue: Whitespace in xsi:type
===================================
Adding space characters to the front or end of type names is accepted by
Xerces. But adding other whitespace chars (TAB, CR, LF) is not accepted:

Message: type '? UIntegerT' specified in 'xsi:type' cannot be resolved

Second issue: xsi:type does not seem work in the main element
=============================================================
Xerces complains:

Message: type of element 'Datatype' is abstract; use 'xsi:type' to specify
