// Return attributes and values of a node in a convenient way:
/* example: 
    <ExampleElement attr1="15" attr2>
    {   attr1: {
            hasValue: true,
            value: 15

        attr2: {

        }
Inclusion of hasValue is in case an eslint rule cares about boolean values
explicitly assigned to attribute vs the attribute being used as a flag
