My work started because SOAP::WSDL 1.0 was so poor, and I needed a
good SOAP implementation. There was no response to my improvement
suggestions. A few month later, however, Martin Kutter picked-up
his pieces and started with his 2.0 implementation. I was quite
far underway already.
The three implementations (SOAP::Lite/SOAP::WSDL/XML::Compile) are very
different. Some key differences:
I started with a 100% complete and compliant XML-Schema implementation
based on XML::LibXML. I do not add strong-typing or namespaces to Perl:
the Perl side is just simple nested HASHes with the same structure as
the XML message (and you can have an example Data::Dumper-like template
being generated for you, if you do not want to read the schema).
My SOAP/WSDL interface is as abstract as possible. With WSDL file,
a SOAP message is exchanged in 3 lines of code only: including all
fault processing. And no DWIM: the message is validated to be correct.
To give an example: an "Integer" type must be able to handle at least
18 digits, according to the specs. In my implementation it will be
represented by a BigInt. (Unless you use the 'sloppy_integers'
<element name="x" type="int" maxOccurs="unbounded" />
<list itemType="int" />
are both on the Perl side: x => [13, 42]
(see: no strong typing needed!)
The translator will produce different XML, respectively
