date format: cannot unmarshal into soap.XSDDate

[giuliohome]

I have seen "Date/time types fail to unmarshal" issue #38 and "Xsd date and time support" PR #195
I have noticed xsd:date Datatype Reference https://books.xmlschemata.org/relaxng/ch19-77041.html

[-]CCYY-MM-DD[Z|(+|-)hh:mm]

Note the Example where it is clearly stated that

Valid values include: 2001-10-26,...

I think that the case of a xsd:date like "2023-10-11" - i.e. without the optional T time part - is not covered by the current implementation.
Maybe that's a bug that could be fixed.
Indeed, given a generated struct attribute

  SchemaRevisionDate soap.XSDDate `xml:"schemaRevisionDate,attr,omitempty" json:"schemaRevisionDate,omitempty"

I was getting the error:

could't get change request: cannot unmarshal into soap.XSDDate

Meanwhile I've worked it around by defining

type customDate struct {
	t time.Time
}

func (c *customDate) UnmarshalXMLAttr(attr xml.Attr) error {
	const myFormat = "2006-01-02"
	parse, err := time.Parse(myFormat, attr.Value)
	if err != nil {
		return err
	}
	c.t = parse
	return nil
}
