It would be nice to be able to "reload" the schemas while you have a document open.
For ad-hoc documents, I often have the schema open at the same time I have the document that uses it open. -- 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." Bertrand Russell in a footnote of Principles of Mathematics
