I've implemented a custom ribbon button/dialog to insert a link to a document contained in a third party DMS. The DMS client installs a protocol handler that allows the use of links such as the following -
iwl:dms=DEV85SERVER&lib=LIVE&num=25210&ver=1
Unfortunately, upon saving the page, the above URL is stripped out and I'm left with an empty A tag.
Is it possible to either disable the SP2010 RTE validation, or escape the above URL somehow to prevent the A tag being sanitized?
