Composite interface is non-exported

[etiennelndr]

I am currently creating the ArchiveService and I need to create structures that extend the MAL Composite interface. But there is a little problem: I can't create these structures because the composite() function begins with a lowercase letter. For the moment, the function is non-exported because it is implemented like this:

type Composite interface {
    Element
    composite() Composite
}

Is it possible to change its implementation like this ? (starting with an uppercase)

type Composite interface {
    Element
    Composite() Composite
}

Thank you in advance.

It's true, may be we have a similar problem with Attribute interface.
