Let's say you specify a non-existing export filter during conversion.

Old output:

Error: Please verify input parameters... (SfxBaseModel::impl_store <file:///test.html> failed: 0x81a(Error Area:Io Class:Parameter Code:2074))

New output:

Error: Please verify input parameters... (SfxBaseModel::impl_store <file:///test.html> failed: 0x81a(Error Area:Io Class:Parameter Code:26))

The later (at least) allows going to include/vcl/errcode.hxx, searching
for Io.*Parameter.*26, and leads to ERRCODE_IO_INVALIDPARAMETER.
