May I suggest the following rewording of the sentence in question:

Current:

"The SOAP mustUnderstand attribute is useful for detecting situations in 
which required software is not available at a node which has been 
correctly targeted;"

Suggested

"The SOAP mustUnderstand attribute is useful for detecting situations in 
which a SOAP block targetted at a node is not understood (see 2.4 
Undestanding SOAP Headers) by that node;"

The first paragraph of 2.4 contains the following sentence which 
explains the meaning of "understand" in this context:

"We say that a SOAP header block is understood by a SOAP node if the 
software at that SOAP node has been written to fully conform to and 
implement the semantics conveyed by the combination of local name and 
namespace name of the outer-most element information item of that block."

Regards,
Marc.
