Current behavior

Exporting descriptions containing xhtml tables from inside a template does not work, following construct leads to the error below:

{ m:template showDescriptions(top:capellamodeller::SystemEngineering) }
{ m:for fkt | top.eAllContents(pa::PhysicalFunction) }
{ m:if not fkt.description.trim().equals('') and fkt.description.trim()->size() > 0 }
{ m: fkt.description.trim().fromHTMLBodyString() }
{ m:else }
- 
{ m:endif }
{ m:endfor }
{ m:endtemplate }

{ m:mySystemEngineering.showDescriptions() }

Error:

M2Doc : technical error.

Expected behavior

Should export the description the same as without template:

{ m:for fkt | mySystemEngineering.eAllContents(pa::PhysicalFunction) }
{ m:if not fkt.description.trim().equals('') and fkt.description.trim()->size() > 0 }
{ m: fkt.description.trim().fromHTMLBodyString() }
{ m:else }
- 
{ m:endif }
{ m:endfor }

Minimal reproduction of the problem with instructions

see attached Capella 5.2 project: M2DocTableInFunctionDescriptionOutput.zip

1. version with direct export that actually works: generate with DirectDescriptionOutput.genconf
2. version with template that produces the error: generate with TemplateForDescriptionOutput.genconf

What is the motivation / use case for changing the behavior?

Direct export and export from template should work the same way.

Environment

M2Doc version: 3.2.1
Eclipse version: Capella 5.2
Platform version:  Windows 11
(same error with M2Doc 3.3.0/Capella 6.1)

I reproduce this error with M2Doc 3.3.0.
