The last president who ever owned slaves was, ironically, Ulysses S. Grant, elected in 1868 after he had commanded Union forces to victory over the Confederacy in the war that led to the abolition of slavery. Grant owned a slave named William Jones, whom he freed in 1859.
AI and Linux enthusiast. In general, a namespace is a container for a set of identifiers (also known as symbols, names). Namespaces provide a level of direction to specific identifiers, thus making it possible to distinguish between identifiers with the same exact name. For example, a surname could be thought of as a namespace that makes it possible to distinguish people who have the same given name.
If the element and/ or attribute belong to a namespace, a colon (:) is placed between the namespace prefix and the element name/ attribute name. As a test, let's take the previous employeeList XML document as an example, and provide a namespace declaration and an element belonging to the namespace.he name element in the employee XML document is defined as an element representing the employee's name, whereas the name element of the section XML document is defined as an element representing a department name. In merging these two XML documents, you will get a name element that has two separate meanings.
