Equivalent of SyntaxNormalizer

[FrediKats]

Roslyn provides API for normalization whitespaces: https://github.com/dotnet/roslyn/blob/8e4ab418a8f9703f7dfe3a66adc9b3876ef9382f/src/Compilers/CSharp/Portable/Syntax/SyntaxNormalizer.cs#L14

Is this any equivalent of this behavior for XmlParser? My use case:

1. Parse tree
2. Add node
3. Call .NormalizeWhitespace or smth like this
4. Get Xml with formatter indentations

In source code I found public static class Normalization but look like this normalization works only for attributes.

I'm afraid we don't have a formatter currently.
