Subject: Problem:
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=faf67a63d77899545c58be1fa0969e95aa85df08;p=docbook-dsssl

Problem:
Garbage characters appear in content of Title attribute in HTML
output.

Cause:
Contents of Alt element, including line breaks, were being copied
over "as is" to value of Title attribute in HTML output. Line
breaks in Title appear a garbage characters when displayed as
pop-up "tool text".

Fix:
Added call to normalize-space() when transforming content of Alt
for HTML output. Closes #1254532. Thanks to Sam Steingold for
reporting the problem.
