I have a question regarding the use of empty-element tags. I have an XML
document that contains some elements that at times may be empty. I was
reading that it's illegal in XML to use start/end tags with empty elements.
Is this true and if so, I assume that I can alternate between start/end tag
and empty-element tags, correct? I am pretty new to XML and I'd appreciate
any input that would help me to produce good, well structured files.
