As of January 12, 2025, PWCT2 will check rules (defined by each component) to determine the allowed parents and children. This functionality was previously applied in PWCT1 and is now implemented in PWCT2 as well. This prevents composition errors; for example, (Else) or (Elseif) components can't be added outside the (If) component.

In PWCT1 we provide two modes 1. (Free Editor + VPL Compiler) which allows syntax errors and can detect them 2. (Syntax Directed Editor) which prevent errors.

In PWCT2 at the current stage we provide (Free Editor), The (VPL Compiler) will be added to detect errors and the SDE will be added to prevent them as we did in PWCT1.
