[BUG] Simple xsl:fo crashes pdf component

Aspose.PDF Product Family
1

Hi, could you explain to me why this xsl:fo crashes the pdf generator?
Tested with 17.12.0. Works with other components

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>
	<fo:simple-page-master master-name="A4" page-width="210mm" page-height="297mm">
		<fo:region-body/>
	</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="A4">
	<fo:flow flow-name="xsl-region-body">
		<fo:block white-space-collapse="false" white-space-treatment="preserve" linefeed-treatment="preserve">
			<fo:block text-align="center">
				<fo:inline>Part II</fo:inline>
			</fo:block>
		</fo:block>
	</fo:flow>
</fo:page-sequence>
</fo:root>

Thanks
Martin

@Martin_Osterberg,

An online XSL - FO validator shows the parsing error as follows: image.png (1.4 KB). Please review the XSL-FO content, and then let us know if Aspose.Pdf API does not recognize a valid XSL-FO file.

Hi Imran,

The validator you used is for xslt, this is xsl:fo.
You can use this validator at the bottom of the page:

The xsl:fo is valid according to this.

Best regards
Martin

Thanks for giving this more attention.
Regarding paid support, spending $10k on a pdf component one would think it should be able to handle centered text while also preserving multiple spaces without crashing.
