[xml] Inserting document fragment

[Kris Breuker <kris b-lex nl>]

Hi,

When I insert a document fragment node (XML_DOCUMENT_FRAG_NODE) into the 
XML tree (for example using xmlAddChild), the node itself gets inserted 
instead of its child nodes. This is a bit inconvenient because I am 
writing a DOM api for a scripting language we're developing here, and 
the specification 
(http://www.w3.org/TR/DOM-Level-2-Core/core.html#ID-B63ED1A3) states:

> Furthermore, various operations -- such as inserting nodes as
> children of another Node -- may take DocumentFragment objects as
> arguments; this results in all the child nodes of the
> DocumentFragment being moved to the child list of this node.

I know I can use xmlAddChildList with the children property of the 
document fragment node, but there are no such functions for 
xmlAddPrevSibling (i.e. xmlAddPrevSiblingList). Is there an easy way of 
inserting the children of a document fragment instead of the document 
fragment itself?
