Description:
------------
First : my PHP version is 5.6.19, but it's not listed above.
When using DOMNode::replaceChild or DOMNode::appendChild or DOMNode::insertBefore in order to insert a node which includes long namespace prefixes (ex. : "variable_trade_item_information:variableTradeItemInformationModule"), the prefix is truncate to 20 characters. In this example it becomes "variable_trade_item_:variableTradeItemInformationModule".

When inserting such a node, DOM also adds in the root tag of the node all the definitions of the prefix used in the node. This bunch of prefix definitions  include the same truncated prefixes.
May be this header is created because the truncated prefixes are not declared (after they have been truncated), as their definitions in the tag itself are not truncated. Ex; : <variable_trade_item_:variableTradeItemInformationModule xmlns:variable_trade_item_information="urn:gs1:gdsn:variable_trade_item_information:xsd:3" ... (snipped) >

Test script:
---------------
Sorry but my test script depends on large XML file...

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.
