Hello,
I'm trying to modify
schema/libreoffice/OpenDocument-v1.3+libreoffice-schema.rng to add a
new attribute to number:text
I added:
<rng:define name="number-text" combine="interleave">
<rng:ref name="number-text-attlist"/>
</rng:define>
<rng:define name="number-text-attlist">
<rng:interleave>
<rng:optional>
<rng:attribute name="loext:blank-width-char">
<rng:ref name="string"/>
</rng:attribute>
</rng:optional>
</rng:interleave>
</rng:define>
But I got the following error:
.../schema/libreoffice/OpenDocument-v1.3+libreoffice-schema.rng[7078,43]: Fatal: <attribute> is grouped and that group is repeated
The line number corresponds to nothing, and if I move the upper code
on a different place in the file, the error is always at this unknown
7078th line. >
Any idea about what I could try?
The line 7078 belongs to <rng:element name="number:date-style">
That can have several <rng:ref name="number-text-with-fillchar"/>.
Such is in line 7427. It can have several <rng:ref name="number-text"/>.
Currently all together resolves to several <rng:element
name="number:text"> and <rng:element name="number:fill-character">. So
currently <number:date-style> element can have several child elements
<number:text>. That is no problem, because several child elements with
the same name are possible.
Now you introduce an attribute into <rng:ref name="number-text"/>. That
means, that when resolving it for <number:date-style> element this would
get several attributes with the same name. And that is not possible.
You need to look, to which element your new attribute belongs.
if it should go on the numer:text element, it needs to be a child of its
rng:element - currently it's not extensible (via "combine" feature):
<rng:define name="number-text">
<rng:element name="number:text">
<rng:text/>
</rng:element>
</rng:define>
so you have to override it - at the start of the libreoffice schema
there is an rng:include, paste the above into this include element and
adapt it - this will override what is in the included file.
