4.10.8.2 Protocol Specific Transformation Style Sheet (xsl)

As shown in the structural overview picture above, the protocol specific FDT specification extension covers a transformation style sheet (.xsl) in addition to schemas. This xsl is to be used by a Frame Application in order to convert the protocol specific formats included in the identification (scan and DTM) XML documents into strings. The result must be validated against the protocol independent FDT Schemas (DTMScanIdentSchema and DTMDeviceTypeIdentSchema). The output can be used by a Frame Application to compare scan and DTM values based on string format. A DTM may define a range of supported physical device types by including regular expressions. In order to identify a matching DTMDeviceType, a Frame Application must implement a pattern matching according to the regular expression syntax defined below.
