Claim:
A structured document described in a meta language, the document being comprised of computer-readable code stored on a computer-readable storage medium that is executed by an information processing device to display data and comprising: a first identifier for the information processing device to identify a first markup language; a second identifier nested in the first identifier for the information processing device to identify a second markup language, the second identifier being used when the information processing device cannot understand the first markup language but can understand the second markup language; first data described in the first markup language; and second data which is described in the second markup language, and which is an external reference to an image corresponding to the first data, where the image has previously been generated by converting a result obtained upon processing the first data described in the first markup language into image data in advance of a processing of the structured document by the information processing device, wherein, the information processing device parses the document to determine if the first markup language can be understood by the information processing apparatus, and, if the first markup language cannot be understood by the information processing apparatus, the information processing device executes a processing of the second data to display the image which has previously been generated instead of processing the first data to be displayed.
