[Bug]: Including redundant xmlns field when generating records from an xml value

[Nuvindu]

Description

When generating records from an XML value, a redundant field 'xmlns is added to the record even though it is not necessary. This issue occurs when XML elements include namespace declarations, leading to an additional field being generated for the default namespace attribute. The redundant field causes data mapping issues.

**Input XML: **

<h:TimeStamp xmlns:h="http://htng.org/1.3/Header/" xmlns="http://htng.org/1.3/Header/">2024-07-04T15:37:45.3605563Z</h:TimeStamp>

**Generated record: **

@xmldata:Namespace {prefix: "h", uri: "http://htng.org/1.3/Header/"}
type H_TimeStamp record {
    string \#content;
    @xmldata:Attribute
    string 'xmlns;
};

**Expected record: **

@xmldata:Namespace {prefix: "h", uri: "http://htng.org/1.3/Header/"}
type H_TimeStamp record {
    string \#content;
};

Steps to Reproduce

1. Provide an XML value with a namespace declaration (e.g., xmlns="http://example.org").

2. Use the record generation tool to create a record from the XML.

3. Observe that the generated record includes a redundant xmlns field.
