Problem statement

When using abbreviations (in my case PDF) and x-go-name, non-compiled code is generated.

Example: a parameter named pdf_extraction_mode (translated to a literal PdfExtractionMode) and its x-go-name PDFExtractionMode.

The code in the *Params structure is generated correctly (the name is the same as in x-go-name), however, in the generated SetDefaults code, the PdfExtractionMode literal is substituted, which breaks the compilation.

$ go build ./client/                                                                    
client/operations/extract_pdf_parameters.go:94:3: unknown field 'PdfExtractionMode' in struct literal of type ExtractPdfParams
