Section 5.2.3 of the SOAP 1.2 spec seems to say "true" and "false" are legal.

----------
5.2.3 SOAP mustUnderstand Attribute

The SOAP mustUnderstand attribute information item is used to indicate whether the processing of a SOAP header block is mandatory or optional (see 2.4 Understanding SOAP Header Blocks)

The mustUnderstand attribute information item has the following XML infoset properties:

    *

      A [local name] of mustUnderstand .
    *

      A [namespace name] of "http://www.w3.org/2003/05/soap-envelope";.
    *

      A [specified] property with a value of "true".

The type of the mustUnderstand attribute information item is xs:boolean.

Omitting this attribute information item is defined as being semantically equivalent to including it with a value of "false".

SOAP senders SHOULD NOT generate, but SOAP receivers MUST accept the SOAP mustUnderstand attribute information item with a value of "false" or "0".

If generating a SOAP mustUnderstand attribute information item, a SOAP sender SHOULD use the canonical representation "true" of the attribute value (see XML Schema [XML Schema Part 2]). A SOAP receiver MUST accept any valid lexical representation of the attribute value.

If relaying the message, a SOAP intermediary MAY substitute "true" for the value "1", or "false" for "0". In addition, a SOAP intermediary MAY omit a SOAP mustUnderstand attribute information item if its value is "false" (see 2.7 Relaying SOAP Messages).

A SOAP sender generating a SOAP message SHOULD use the mustUnderstand attribute information item only on SOAP header blocks. A SOAP receiver MUST ignore this attribute information item if it appears on descendants of a SOAP header block or on a SOAP body child element information item (or its descendents).
