Align HTML style names to default template

[spoeschel]

The default DOCX template declares the names of the HTML related styles like e.g. HTML Typewriter in /word/styles.xml (within the DOCX/ZIP). However the document.pr-d.xsl maps e.g. DITA's codeph element to the style HTMLTypewriter (note the missing space).

As the default template only declares (but not defines) e.g. HTML Typewriter, the output will look the same also with the aligned style name. But when that style is explicitely added to the default template or a custom template with the style is used, this would enable the intended (monospace) formatting.

Therefore it would be great if such style names in the document.pr-d.xsl could be fixed/aligned to the respective style names of the default template's styles.xml.
