Re: [libreoffice-accessibility] Default language of hyperlinks

Hi :)
I think that post should have gone to the users list rather than this one as 
there might be people there able to help.  Hmmm, actually perhaps just posting 
it as a bug-report would be better?

Regards from
Tom :)

Subject: [libreoffice-accessibility] Default language of hyperlinks

Hi,

When you create a hyperlink in a Writer document (LibreOffice or OpenOffce.org), 
the language is explicitly set to "zxx" by default (this is shown in the 
statusbar as "[None]"). In order to identify the language of a hyperlink, you 
need to explicitly set it by selecting the link and picking a language.

The cause seems to be a default in Writer. When you unpack an ODT file and 
inspect the file "styles.xml", you will find the following lines:

  <style:style style:name="Internet_20_link" style:display-name="Internet link" 
style:family="text">
   <style:text-properties fo:color="#000080" fo:language="zxx" fo:country="none" 
style:text-underline-style="solid" style:text-underline-width="auto" 
style:text-underline-color="font-color" style:language-asian="zxx" 
style:country-asian="none" style:language-complex="zxx" 
style:country-complex="none"/>
  </style:style>

The relevant attributes here are
* fo:language="zxx" fo:country="none"
* style:language-asian="zxx" style:country-asian="none"
* style:language-complex="zxx" style:country-complex="none"

It is unclear to me why these defaults exist. I could not find anything in the 
ODF 1.2 specification that justifies their existence.
Some background from that specification (notably section 16.2<style:style>):

"Styles defined by the <style:style> element use a hierarchical style model. The 
<style:style> element supports inheritance of formatting properties by a style 
from its parent style. A parent style is specified by the 
style:parent-style-name attribute on a <style:style> element."

(Note that the style:style element for hyperlinks does not have a 
style:parent-style-name attribute.)

"For styles with family text which are applied to elements which are contained 
in another element that specifies a style with family text, the search continues 
within the text style that is applied to the nearest ancestor element that 
specifies a style with family text, and continues in its parent styles."

Based on this I would expect hyperlinks to inherit language properties from the 
paragraph within which it is contained. In my test document, they would inherit
* fo:language="en" fo:country="GB"
* style:language-asian="zh" style:country-asian="CN"
* style:language-complex="ar" style:country-complex="SA"
(I always enable East-Asian and CTL in Writer, and set the default language for 
Asian languages to "Chinese (simplified)".)
However, the default hyperlink styles appear to prevent this.

Authors usually forget to set the language of hyperlinks, so I would be in 
favour of removing the defaults that set the language of hyperlink text to "zxx" 
/ "[None]".

Best regards,

Christophe
