serde deserialize, attribute and child element share the same name

i have a funny problem parsing COLLADA xml documents:

<skin source="#Cylinder_002-mesh">
        <source id="Armature_JointBase_001-skin-joints"> .. </source>
</skin>

And i is not clear how the Rust code has to look to parse something like this.

My naive approach was something like this:

#[derive(Deserialize)]
pub struct Skin {
    #[serde(rename = "source")]
    pub sources: Vec<SkinSource>,
}

#[derive(Deserialize)]
pub enum SkinSource {
    Source{id: String},
    Attr(String),
}

But this did not work.

Since version 0.27.0 this is solved by prepending @ to the names of attributes. The original task can be solved by this types:

#[derive(Deserialize)]
pub struct Skin {
    #[serde(rename = "@source")]
    pub source: String,

    #[serde(rename = "source")]
    pub sources: Vec<SkinSource>,
}

#[derive(Deserialize)]
pub struct SkinSource {
    #[serde(rename = "@id")]
    id: String,
}

Fixed by #490.
