I understand better now. Unfortunately I can't think of a way to get
this with XSD/e. Such a feature would require each node in the object
model to store some kind of a map of child nodes to their names. Each
node will also need to store a reference to its parent so that the
whole model can be traversed from a child to its ultimate parent
(this description should actually remind us of something that has
these properties -- DOM). So as you can see, this feature would
require quite an elaborate data structure. And this is without even
thinking about fundamental types (what if year is int, how can one
possibly store a reference to parent there?). 

One way to make this problem more tractable would be to require a
schema to define a unique type for each element/attribute. Then you
could create a map between types and their XPath expressions. In
fact, if you make each type name encode its XPath, then you could
derive the XPath expression directly from typeid(book.year).name().
For example, if year's type is book_year_t, then you could easily
convert it to the book/year XPath expression.

You could also probably achieve something like this with XSD using
the DOM association feature (maintains an association between DOM
and object model nodes). Though the DOM association is not
automatically updated when the object model is modified.

I double-checked everything and have deleted and re-created new
projects numerous times and they are all failing the same way with the
same errors

When following the instructions, though, I cannot save the "libsxde"
dir when creating the project becuase it overwrites (as the
instructions say is okay, but ends up nuking src and xsde dirs). So I
have had to bring import the xsde dir and files as well as src

Second the default compiler is Apple LLVM compiler 3.0 and I manually
changed this to LLVM GCC 4.2 (those being the only two actual
options). I assume it is something to do with the compiler and/or some
other flags that need to be set.

Anyone have any ideas what I can do to get this working? This project
looks absolutely perfect for me so I would dearly like to use it.
Thanks in advance!

I think what you mean is that you have generated the src directory using
make and then you are trying to create an XCode project to build libxsde.
Right?

I guess this is a new "feature" in the later XCode versions.

Ok, that's why you have the problem. You must not import the xsde
directory, only src. The src directory contains all the source files
that should be compiled for this configuration. The xsde directory
contains all the source files, for all the configurations, as well
as files that should not be compiled. xmltok_impl.c is one of those
files that should never be compiled directly.

If XCode cleans up everything under libxsde, try to temporarily move
the xsde, src, etc., directories somewhere, create the project, move
them back to libxsde, and then import the src directory only.

That worked perfectly! Thank you for that. Once I created a new
project I copied in the entire libxsde dir into the project folder but
only imported the src dir to the XCode project. It built perfectly and
I was able to build the debug library. Haven't tried to use it yet but
that first step worked so thank you again.

Hi,

I would like to know if it is possible to use xsd:restriction on xsd:any
element with XSD/e?

As an example, I try to process 2 files.
First one (test.xml) is:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:scl="http://www.iec.ch/61850/2003/SCL"
xmlns="http://www.iec.ch/61850/2003/SCL"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.iec.ch/61850/2003/SCL"
elementFormDefault="qualified" attributeFormDefault="unqualified"
version="3.1">
	<xs:complexType name="tAnyContentFromOtherNamespace" abstract="true"
mixed="true">
		<xs:sequence minOccurs="0" maxOccurs="unbounded">
			<xs:any namespace="##other" processContents="lax"/>
		</xs:sequence>
		<xs:anyAttribute namespace="##other" processContents="lax"/>
	</xs:complexType>
</xs:schema>


Second one (test2.xml) is:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns="http://www.xxx.com/IEC61850/SCL"
xmlns:sclext="http://www.xxx.com/IEC61850/SCL"
xmlns:scl="http://www.iec.ch/61850/2003/SCL"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.xxx.com/IEC61850/SCL"
elementFormDefault="qualified" attributeFormDefault="unqualified">
	<xs:import namespace="http://www.iec.ch/61850/2003/SCL"
schemaLocation="test.xsd"/>
	<xs:complexType name="NewType">
		<xs:complexContent mixed="true">
			<xs:restriction base="scl:tAnyContentFromOtherNamespace">
				<xs:sequence minOccurs="0" maxOccurs="unbounded">
					<xs:element name="MyElement" type="xs:int"/>
				</xs:sequence>
			</xs:restriction>
		</xs:complexContent>
	</xs:complexType>
</xs:schema>


I got the following error:
<<
test2.xsd:8:50: error: unable to match restricted particle
>>

When changing "restriction" to "extension", I got another error:
<<
:0:0: error: complex type 'NewType' violates the unique particle
attribution rule in its components '##other' and 'MyElement'
>>

The goal is to get a derived type in order to use polymorphism, without
modifying first file (test.xsd)

Thanks in advance.

Best regards
Antoine

No, this mechanism is not supported by XSD/e. The workaround would be to
introduce an intermediate type:

       <xs:complexType name="BaseType">
                <xs:complexContent mixed="true">

                          </xs:sequence>
                        </xs:restriction>
                </xs:complexContent>

                                        <xs:element name="MyElement" type="xs:int"/>
