Answer:
Syntax Errors: 
No closing tag of the root element. </countryList>
All tags should follow case sensitive, there are a lot of tags like so:

• <OfficialName> U.S </officialName>. This should be fixed to be as following <OfficialName> U.S </OfficialName>
• <Label>Common Names: </label>.This should be fixed to be as following <Label> Common Names</Label>
• <CommonName> U.S </commonName>. This should be fixed to be as following <CommonName> U.S </CommonName>

Also some tags are not properly nested and not properly closed. For example this tag is not properly nested <Label>Capital:</capital>. and so is this <Capital cityNum="1"> Washington, D.C </label>. While the following is not properly closed <Label> Capital: </capital> apart from having capslock differences it also isn't the correct label. 
Another tag which is a syntax error is <2ndCity cityNum ="2"> Mombosa </2ndCity> this tag is not correct as XML tags can contain numbers but cannot start with a number. 


There can't be two same attributes in one tag. <MajorCity cityNum=’6’ cityNum=’7’>Kisumu-Kericho</majorCity> Therefor this is not allowed.
