remove all processed soap header blocks.
remove all non-relayable soap header blocks that were targeted at the forwarding node but ignored during processing.
retain all relayable soap header blocks that were targeted at the forwarding node but ignored during processing.
forwarding soap intermediaries must also obey the specification for the soap forwarding features being used. the specification for each such a feature must describe the required semantics, including the rules describing how the forwarded message is constructed. such rules may describe placement of inserted or reinserted soap header blocks. inserted soap header blocks might be indistinguishable from one or more of the header blocks removed by the intermediary. processing is defined here in terms of re-inserting header blocks （rather than leaving them in place) to emphasize the need to process them at each soap node along the soap message path.
2.7.2.1 relayed infoset
this section describes the behavior of soap forwarding intermediaries with respect to preservation of the xml infoset properties of a relayed soap message.
unless overridden by the processing of soap features at an intermediary （see 2.7.2 soap forwarding intermediaries), the following rules apply:
all xml infoset properties of a message must be preserved, except as specified in rules 2 through 22.
the element information item for a header block targeted at an intermediary may be removed, by that intermediary, from the [children] property of the soap header element information item as detailed in 2.7.2 soap forwarding intermediaries.
element information items for additional header blocks may be added to the [children] property of the soap header element information item as detailed in 2.7.2 soap forwarding intermediaries.
in this case, a soap header element information item may be added, as the first member of the [children] property of the soap envelope element information item, if it is not already present.
white space character information items may be removed from the [children] property of the soap envelope element information item.
white space character information items may be added to the [children] property of the soap envelope element information item.
white space character information items may be removed from the [children] property of the soap header element information item.
white space character information items may be added to the [children] property of the soap header element information item.
comment information items may be added to the [children] property of the soap envelope element information item.
comment information items may be removed from the [children] property of the soap envelope element information item.
comment information items may be added to the [children] property of the soap header element information item.
comment information items may be removed from the [children] property of the soap header element information item.
attribute information items may be added to the [attributes] property of the soap envelope element information item.
attribute information items may be added to the [attributes] property of the soap header element information item.
attribute information items may be added to the [namespace attributes] property of the soap envelope element information item.
attribute information items may be added to the [namespace attributes] property of the soap header element information item.
soap role attribute information items that are present in the [attributes] property of soap header block element information items may be transformed as described in 5.2.2 soap role attribute.
soap mustunderstand attribute information items that are present in the [attributes] property of soap header block element information items may be transformed as described in 5.2.3 soap mustunderstand attribute.
soap relay attribute information items that are present in the [attributes] property of soap header block element information items may be transformed as described in 5.2.4 soap relay attribute.
the [base uri] property of the document information item need not be maintained.
the [base uri] property of element information items may be changed or removed.
the [character encoding scheme] property of the document information item may be changed or removed.
all namespace information items in the [in-scope namespaces] of element information items must be preserved. additional namespace information items may be added.
上面定义了哪些infoset在relay时可以被新消息采用，哪些可以放弃，请问谁知道这些infoset具体在什么情况下被采用/放弃？谁能举个例子 |
