Question regarding C14N namespace

[jacksuyu]

I am a little confused about "Elimination of superfluous namespace
declarations" in the w3c C14 document.

Couple sample situations:
1.
<ParentNode xmlns="parent" xmlns:C="child">
<C:TheNode>
</C:TheNode>
</ParentNode>

If I perform C14N process on C:TheNode, will it be
<C:TheNode xmlns:C="child">
</C:TheNode>
Or just
<C:TheNode>
</C:TheNode>

2. Useless namespace
<C:TheNode xmlns:C="child" xmlns:junk="junkURI">
</C:TheNode>

After C14N process, should it be
<C:TheNode xmlns:C="child">
</C:TheNode>
or
<C:TheNode xmlns:C="child" xmlns:junk="junkURI">
</C:TheNode>


Thanks.

One more question regarding C14N, shouldn't the line breaks in elements
be changed to #xA #xD ?

Such as
<C:TheNode xmlns:C="child" xmlns:junk="junkURI">
</C:TheNode>

should be CN14 to
<C:TheNode xmlns:C="child" xmlns:junk="junkURI"> #xA </C:TheNode>

Thanks
