In certain MathML constructs (e.g. mfenced) there are a number of child elements that make up the construct and need to be rendered. Any text between those child elements should be ignored. In fact, non-whitespace text in the wrong place is most certainly incorrect but something that can be recovered from. I don't want to remove the text from the DOM nodes but I need to keep the RenderText instances from being created or displayed. What is the correct way to do this? I've been trying to handle this in the renderer but it seems like that is really too late. I though about changing the attach method to exclude such ignorable text. -- --Alex Milowski "The excellence of grammar as a guide is proportional to the paucity of the inflexions, i.e. to the degree of analysis effected by the language considered."
