Possible bug in staticcheck - where should I report it?

Given:

type XMLFile struct {
	XMLName      xml.Name `xml:",any"`
	ID           string   `xml:"id,attr"`
	Path         string   `xml:"path"`
	OriginalPath string   `xml:"originalPath"`
	Extension    string   `xml:"extension"`
	MimeType     string   `xml:"mimeType"`
	Data         []byte   `xml:"data,omitempty"`
}

The linter complains as SA5008: invalid XML tag: cannot use option any on XMLName field. AFAIU, according to the Go encoding/xml documentation, the ,any option is valid for fields of typexml.Name and is used to match any XML element. This is a common pattern for handling arbitrary XML elements.

You should open an issue on the staticcheck repository: https://github.com/dominikh/go-tools

But I cannot see something related specifically to xml.Name and any inside the encoding/xml documentation.
I can only see references to attributes and sub-elements. A tag name is neither an attribute nor a sub-element.

• If the XML element has an attribute not handled by the previous rule and the struct has a field with an associated tag containing ",any,attr", Unmarshal records the attribute value in the first such field.
  ...
• If the XML element contains a sub-element that hasn't matched any of the above rules and the struct has a field with tag ",any", unmarshal maps the sub-element to that struct field.

Indeed. My bad. That's not a bug. 👍
