Adding custom tags to XML documnetation intellisense?

[Graham Parkings]

Hi all, Ive recently taken to including Pseudocode in the XML documentation tags (largely because i want a live design document). For this i use a tag which is picked up by my XSLT used to create nice looking docs. This works fine but i would like to have the tag included in the intellisense pop-up (because i often mispell it and dont notice). Does anyone know a way to add the tag to intellisense?, i have tried code snippets but they are filtered out for XML doc tags Thanks, Graham
