You might need to change a text or icon for some Elements(nodes) in trees. For example, the adorn standard Element icon for showing that Element is annotated like the Validation framework does.
Option #1 for changing just a text
The text can be changed using a custom representation provider as described in Creating textual element representation. Using this approach, the text will be changed everywhere in UI, not just in trees.
Option #2 for changing a node text or icon
Use com.nomagic.magicdraw.ui.browser.TreeNodeAdornmentManager.addIconAdornment(IconAdornment) to register a node icon customizer.
Use TreeNodeAdornmentManager.addTextAdornment(TextAdornment) to register a node text customizer.
