General
-------
- rename soapobject to soapclient
- make sure soapvar and soapparam are really need
- make sure soapserver.map(), soap_encode_to_xml() and soap_encode_to_zval() are really need
- reimplement SoapObject::__getfunctions() and SoapObject::__gettypes()
  to return structures instead of strings

SOAP
----
+ SOAP versioning model
+ SOAP message must not contain a Document Type Declaration
- SOAP message MUST NOT contain Processing Instructions <?xml-stylesheet ... ?> (XML_PI_NODE)
- SOAP 1.1 fault codes ("client","server"), SOAP 1.1 fault codes ("Sender","Receiver")
+ SOAP 1.1 Content-Type - "text/xml", SOAP 1.2 - "application/soap+xml"
- support for SOAP headers
  - actor attribute
  - mustUnderstend attribute
- make sure soap 1.1 and 1.2 are supported fully

Encoding
--------
- full support for standard simple types (
  + anyType
  + anyURI, 
  + QName, 
  + NOTATION,
  + normalizedString, 
  + token, 
  ? language, (pattern: "[a-zA-Z]{1,8}(-[a-zA-Z0-9]{1,8})*")
  ? NMTOKEN, (pattern: "\c+") (\c: [a-zA-Z0-9.\-_:])
  ? NMTOKENS, (list: NMTOKEN, minLength: 1)
  ? Name, (pattern: "\i\c*") (\i: [a-zA-Z_:]
  ? NCName, (pattern: "[\i-[:]][\c-[:]]*")
  ? ID, (base: NCName)
  ? IDREF, (base: NCName)
  ? IDREFS, (list: IDREF; minLength: 1) 
  ? ENTITY, (base: NCName)
  ? ENTITIES,  (list: ENTITY; minLength: 1) 
  ? duration, 
  + unsignedLong)
- full support for standard date/time types (
  ? dateTime,
  ? time,
  ? date,
  ? gYearMonth,
  ? gYear,
  ? gMonthDay,
  ? gDay,
  ? gMonth)
? proper encoding of standard hexBinary type
? proper encoding of standard base64Binary type
- full support for arrays
  + arrayType attribute
  + offset attribute
  + position attribute
  + multidimensional arrays
  + arrays of arrays
	- SOAP 1.2 array encoding/decoding (itemType, arraySize)
  - SOAP 1.1 - arrayType="xsd:ur-type[]", SOAP 1.2 - itemType="xsd:anyType"
  - SOAP 1.1 encoding of arrays with holes (partially transmitted and sparse arrays)
	  SOAP 1.2 doesn't support partially transmitted and sparse arrays
- full support for structures???  
+ references (id,href)
- references to external resources
- default values
- root attribute
? provide schema 1999/2001 support???
? make internal refrences for soap encoding (use seralization logic)???
? provide user space overriding of serialization certin objects and types???
