Is it possible to add
URLEncode to a field in schema.xml, and update the SharePoint site without deleting everything based on the schema? Eg.
<Field DisplayName="Internal/External" />
<Field DisplayName="Internal/External" URLENcode="true" />
I'd like to change it due to WSS not validating soap/xml on output, and having the ' / ' symbol in an attribute name will cause the XML parsing to fail in my client application.
