Re: [xsl] Generating XSD Schema files from XML source files

[Mukul Gandhi <gandhi.mukul@xxxxxxxxx>]

I agree with everything what Mike has said.

Adding to Mike's explanation, here's a little example illustrating
some of the issues you might face with this task.

Let's say there is an instance XML document like following:

<x>100</x>

Then all the below XML schema fragments will successfully validate the
above instance document:

<xs:element name="x" type="xs:integer" />

<xs:element name="x" type="xs:positiveInteger" />

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

or even

<xs:element name="x">
    <xs:simpleType>
        <xs:restriction base="xs:integer">
           <xs:maxInclusive value="1000" />
        </xs:restriction>
    </xs:simpleType>
</xs:element>

For more involved XML documents, difficulty of this task may increase
exponentially :)

generating the Schema file.
