There's actually quite a bit it doesn't support, have a look at the TODO from the source

General

• 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
• error handling???

SOAP

• SOAP routing
• root attribute (it is defined by SOAP 1.1, but not SOAP 1.2)
• make sure soap 1.1 and 1.2 are supported fully

Encoding

? full support for standard simple types (
? 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)
? full support for standard date/time types (
? dateTime,
? time,
? date,
? gYearMonth,
? gYear,
? gMonthDay,
? gDay,
? gMonth)
? full support for arrays

• SOAP 1.1 encoding of arrays with holes (partially transmitted and sparse arrays)
  SOAP 1.2 doesn't support partially transmitted and sparse arrays
  • references to external resources
    ? support for "nillable" and "nil"
    ? default values of
    ? provide schema 1999/2001 support???
    ? make internal refrences for soap encoding (use seralization logic)???
    ? provide user space overriding of serialization certin objects and types???

WSDL

? server part support for "document" style encoding
? support for , soap:fault
? soap:headerfault

• soap:body parts attribute (with MIME/DIME binding)
• MIME binding
• DIME binding
• support for portType/operation parameterOrder attribute
• support for binding operation input/output name attribute (part of overloading)
• function/method overloading/redeclaration (test(int); test(string))
• wsdl auto generation
• HTTP GET/POST binding
• SOAP security extension

Schema

• ? support for user defined simple types ? restiction ? enumeration ? length (for string, anyURI, hexBinary, base64Binary and derived) list??? ? minLength (for string, hexBinary, base64Binary and derived) list??? ? maxLength (for string, hexBinary, base64Binary and derived) list??? + whiteSpace (preserve, replace [#x9,#xA,#xD=>#x20], collapse [replace+?]) - pattern - minExclusive (for numeric, date types) - minInclusive (for numeric, date types) - maxExclusive (for numeric, date types) - maxInclusive (for numeric, date types) - totalDigits (for decimal) - fractionDigits (for decimal) ? union ? support for user defined complex types ? full support for content model encoding/decoding - -

Transport

? HTTP status codes
? HTTP chunked Transfer-Encoding
? support for HTTP compression (gzip,x-gzip,defalte)

• transport abstraction layer???

Interop Testing

• more interop rounds/groups

UDDI

• ???

Thanks for a detailed list of php soap server's limitations.
