Question

Using the custom XML tags “Customers”, “Customer”, “CustId”, “CustName, “CustCity”, “CustState”, and “CustEMail” complete the document below. The “Customers” tag contains zero or more “Customer” children and the “Customer” tag may contain all of the remaining tags as children.

The image depicts an XML document structure used for storing customer information. Below is a transcription of the XML code and an explanation of the embedded diagram.

### XML Code Transcription:

```xml
<?xml version="1.0" encoding="UTF-8"?>
<Customers>
    <Customer>
        <CustId>12334</CustId>
        <CustName>Mary J. Smith</CustName>
        <CustCity>Topeka</CustCity>
        <CustState>KS</CustState>
        <CustEMail>railfan@somemail.org</CustEMail>
    </Customer>
    <Customer>
        <CustId>65443</CustId>
        <CustName>John Q. Adams</CustName>
        <CustCity>Winslow</CustCity>
        <CustState>AZ</CustState>
        <CustEMail>onacorner@examplemail.net</CustEMail>
    </Customer>
</Customers>
```

### Explanation of the XML Structure:

1. **XML Declaration**: 
   - The document begins with `<?xml version="1.0" encoding="UTF-8"?>`, which defines the XML version and character encoding.

2. **Root Element**:
   - `<Customers>`: This is the root element containing all customer records.

3. **Customer Records**:
   - Each customer is encapsulated within `<Customer>` tags.
   - Within each `<Customer>`, the following elements describe customer attributes:
     - `<CustId>`: Customer ID.
     - `<CustName>`: Name of the customer.
     - `<CustCity>`: City where the customer resides.
     - `<CustState>`: State where the customer resides.
     - `<CustEMail>`: Customer's email address.

4. **Sample Data**:
   - The XML contains two customer records with different IDs, names, cities, states, and email addresses.

### Diagram Explanation:

The diagram shown in the image is a drag-and-drop interface, likely used for educational purposes to teach about XML structures. It includes various XML tags such as `<CustCity>`, `<CustName>`, `<Customer>`, `<CustId>`, `<CustEMail>`, `<CustState>`, and `Customers`. These labels help users to understand or create an XML document by placing the tags in appropriate positions to structure the data correctly.
