Menu View → Show Tags in XMLmind XML Editor - Online Help allows to display element tags in a styled view. But what if you don't want this to happen for some elements?

Extension property hide-tags allows to specify this. MathML example:

mml|semantics,
mml|annotation,
mml|annotation-xml {
    display: block;
    hide-tags: yes;
    margin-top: 1.33ex;
    margin-bottom: 1.33ex;
}

The value of this property may be yes or no. Initially, its value is no.

This property is not inherited and cannot be inherited by specifying keyword inherit.
