Declaration
function OpenTag(const Tag: string; const params: TStringList): Integer;

Description
This is the most important function when creating an XML file in code. It creates a open XML tag with certain parameters. If you want to create a closed XML tag use WriteTag instead.
The result value is a unique integer which can be used for CloseTagID. Open tags should be closed with CloseTag but the engine automatically closes tags, too: Example:

OpenTag('p'); OpenTag('b'); WriteText('Test'); CloseTag('p');

... creates the XML code:
>p<>b<Test>/b<>/p<
