XML/Ada includes support for parsing XML files, including DTDs, full support for \
SAX, and an almost complete support for the core part of the DOM. It includes \
support for validating XML files with XML schemas.

%description devel %{common_description_en}

This package contains source code and linking information for developing
applications that use the XML/Ada library.

Summary:        Static libraries of XML/Ada
Requires:       %{name}-devel%{?_isa} = %{epoch}:%{version}-%{release}

%description static %{common_description_en}

This package contains the XML/Ada libraries for static linking. It is needed
for linking GPRbuild statically so that GPRbuild will remain functional when
libraries are upgraded.

Other Fedora packages shall require xmlada-devel rather than xmlada-static if
possible.
