Represents the virtual-instrument-data group definition in the MusicXML schema.

The virtual-instrument subelement data is stored in the virtual_instrument_data table, as follows:

• virtual-library element text: field virtual_library
• virtual-name element text: field virtual_name

A virtual_instrument_data record can be:

• part of an instrument-change element stored in the instrument_change table
• part of a score-instrument element stored in the score_instrument table

A virtual_instrument_data record has a join to an instrument_type record that represents the solo and ensemble subelement choice defined in the virtual-instrument-data group. The instrument_type table is a single-inheritance table with a discriminator column instrument_type_type value of solo or ensemble.
