How to Draw this xsd element in Tikz?

Here my WME:

\tikzset{split style/.style={rectangle split, rectangle split parts=2, draw,rectangle split part align={left}}}

 \tikzset{square/.style={draw,minimum size=6mm,anchor=center,inner xsep=0pt,fill=white}}

\node[xshift=-0.15cm, yshift=-1cm] (model_ct) at (model_c){1\ldots1};

My result:

Answer 1

• Your image can be composed by nodes with predefined styles
• Defined are three nodes style: M (with sign -), T (with sign triangle), N for main nodes with adjustable width.
• Node placements are relative to each other (from top to bottom and from left to right)
